Bradycardia is a common arrhythmia.
Some people in daily life may experience dizziness, weakness, palpitations, chest tightness, shortness of breath, or even fainting and collapse in severe cases when bradycardia suddenly appears and the heart rate drops below 40 beats per minute (bpm).
If bradycardia occurs for a long time, it may cause cardiac arrest and endanger life.
Therefore, once you find unexplained bradycardia, you should pay enough attention to it and seek medical examination in time to avoid deterioration of the situation.
According to the 2018 ACC/AHA/HRS Guideline on the Evaluation and Management of Patients With Bradycardia and Cardiac Delay, bradycardia was redefined as a heart rate of fewer than 50 beats per minute (bpm), compared to a normal heart rate of 50 to 100 bpm. Before this guide, bradycardia referred to a heart rate of fewer than 60 bpm.
When bradycardia occurs, it can be asymptomatic, as it can occur in normal people at rest. On the other hand, it can also occur as dizziness and other discomforts, mainly because the heart's pumping function is weakened due to bradycardia, and it cannot provide sufficient blood supply to our body, especially to the brain, which leads to dizziness and other discomforts. And those serious symptoms are often due to underlying medical conditions.
Ventricular arrhythmias are clinically very dangerous when they occur, except for ventricular premature beats (PVB or PVC), other types of arrhythmias such as ventricular tachycardia, ventricular flutter and ventricular fibrillation are very dangerous. When premature ventricular beats occur, if they are asymptomatic, it does not require treatment, because they are generally not fatal. However, if ventricular tachycardia, ventricular flutter and ventricular fibrillation occur, it is very dangerous in clinical and requires emergency treatment and resuscitation often at an early stage.
When rest at night, healthy adults and children can have bradycardia, which can even reach a heart rate of several 30 beats per minute, especially athletes in good physical condition. So it is common for people who normally work physically or who have been exercising for a long time to have bradycardia. To some extent perhaps a slow heart rate indicates a well-trained indicator. Generally, these people do not have any uncomfortable symptoms, though bradycardia is found during checkups or medical examinations.
Diseases of the heart itself, naturally, can also lead to heart damage, like severe bradycardia. Heart diseases include myocardial infarction (MI), cardiomyopathy, severe myocarditis, sinus node dysfunction, heart block (AV block), etc. People with these heart diseases may have serious bradycardia. Heart disease may even cause syncope and sudden death, which requires special attention.
Infectious diseases, such as typhoid; endocrine system diseases, such as hypothyroidism; central nervous system diseases, such as strokes leading to cranial hypertension; obstructive sleep apnea, mainly manifested by severe snoring and apnea; some patients with a terminal illness, also with a very weak constitution.
Many drugs can inhibit the heartbeat and cause bradycardia, or make bradycardia a side effect, such as digoxin, amiodarone, bisoprolol and some sedative sleeping pills. So the drugs should be taken under the guidance of a doctor.
At what level of slow heartbeat is it time to go to the doctor?
In most cases, a slow heartbeat is benign. Usually, elders are afraid when they notice their heartbeat is slow. In fact, if you observe it and do a little exercise vigorously on your own. And if your heartbeat immediately increases dramatically, it indicates that this fear is not necessary. Therefore, if there are no symptoms and the heart rate is simply low, treatment is not necessary.
However, it should be closely monitored, preferably with a 24-hour continuous ECG monitor. The wearable Wellue's ECG Recorder can monitor your heart's activities for a 24-hour period or longer, recording the dynamic ECG. More importantly, the AI platform can analyze the ECG interpretation so you can know your heart easier and faster without waiting for the busy doctor.
Dynamic electrocardiogram (DCG) is the initial diagnosis to determine whether the patient's symptoms are related to bradycardia and whether they are accompanied by other arrhythmias, which can help the physician in the follow-up diagnosis and treatment.
If the following manifestations occur, you have to ask your doctor because treatment must be given as soon as possible, and some patients will require a permanent pacemaker.
Some people have been told they have ventricular arrhythmia after they have an ECG (electrocardiogram) test in the hospital, so they are scared and asked: is the ventricular arrhythmia serious?
Today, we are going to know something about ventricular arrhythmia.
Ventricular arrhythmias refer to abnormal heart rhythms originating from the ventricles (the lower heart chambers), including premature ventricular beats (premature ventricular contractions), ventricular tachycardia, ventricular flutter and ventricular fibrillation.
Ventricular arrhythmias are clinically very dangerous when they occur, except for ventricular premature beats (PVB or PVC), other types of arrhythmias such as ventricular tachycardia, ventricular flutter and ventricular fibrillation are very dangerous. When premature ventricular beats occur, if they are asymptomatic, it does not require treatment, because they are generally not fatal. However, if ventricular tachycardia, ventricular flutter and ventricular fibrillation occur, it is very dangerous in clinical and requires emergency treatment and resuscitation often at an early stage.
It is the most common clinical arrhythmia that occurs when the ectopic foci of excitation in the ventricular myocardium below the bundle and branches are depolarized prematurely.
It can occur in normal healthy people and patients with various heart diseases and has a wide variability of clinical symptoms and generally good prognosis.
A survey of the general population found that the prevalence of ventricular prematureness detected by general 12 lead ECG was 1%, while that by 24h or 48h ambulatory ECG was as high as 40% to 75%. It can be said that about half of the general population has PVC. The occurrence of ventricular prematureness increases with age and is as high as 69% in people over 75 years of age.
Unlike other types of tachycardia, doctors are very nervous once they see this type of tachycardia because it can be fatal.
Why is ventricular tachycardia fatal? For one, it is most commonly seen in various organic heart diseases such as myocardial infarction, myocarditis, cardiomyopathy, etc. For two, ventricular tachycardia originates in the ventricles and its sequence of excitation is completely opposite to the normal heartbeat, which can affect the efficiency of the ventricles.
Since ventricular tachycardia can lead directly to death, it is said that ventricular tachycardia also means that one's life has sounded the alarm and he must go to see a doctor as soon as possible.
Ventricular flutter and ventricular fibrillation are the direct causes of sudden cardiac death.
Ventricular flutter often precedes ventricular fibrillation, eventually leading to cardiac arrest. Once ventricular flutter occurs, the patient may exhibit sudden loss of consciousness, convulsions, cyanosis associated with the respiratory system, which will eventually lead to death. Physical examination may reveal signs such as the disappearance of heart sounds and pulse beats, undetectable blood pressure, and dilated pupils.
Ventricular fibrillation is a lethal arrhythmia in which the ventricles become disordered, resulting in the loss of regular ventricular excitation and diastolic function.
Patients with arrhythmia may have palpitations, chest tightness, dizziness and other symptoms.
Ensure adequate rest and sleep.
Diet.
- Give fiber-rich foods to prevent constipation.
- Avoid full meals and intake of stimulating foods such as coffee and strong tea.
Monitor ECG daily to prevent serious heart condition.
This heart health monitor can continuously record the ECG for over 24 hours, more portable and light than Holter monitor. Real-time ECG can be read on the phone APP.
Otherwise, AI ECG report is available from PC software, which means sometimes you don't have to spend more time waiting for the doctor's analysis. As far, the following ECG events can be analyzed by the FDA approved Wellue's AI algorithm:
1.PVC(Premature Ventricular Contraction)
2.Couplet of PVC
3.PVC Bigeminy
4.PVC Trigeminy
5.Ventricular Tachycardia
The AI ECG report cannot replace the doctor's diagnosis, but truly helped dotors and patients save time and make patients learn their heart easier.
A resting ECG test in the hospital is effective for heart diagnosis when patients have obvious sudden onset symptoms, but it may not detect any heart abnormalities if they are not present at that time.
The ambulatory ECG by the Holter monitor can continuously record the patient heart's activity under different conditions such as rest, activity, eating, and study for a long time, 24 hours. But it requires 5-7 electrodes absorbed on the chest, which has a greater impact on the user's life.
Nowadays, some wearable ECG monitors are invented to real-time measure the heart's activities for several seconds or minutes. For example, Kardia Mobile ECG Monitor can provide instant ECG on mobile; Wellue PortableECG Monitor with OLED Screen can show real-time ECGs on its OLED screen. However, it didn't solve the problem of long-time monitoring although it is small and light enough to carry.
Is there a wearable ECG monitor that is portable and that can continuously track and record ECG for a long time?
Wellue created its answer. Its wireless ECG Recorder with AI Analysis can be used like a home-use holter monitor but with greater portability and convenience. It can continuously monitor ECG for 24 hours, recording up to 360,000 ECG/EKG signals. Furthermore, the FDA-approved AI ECG algorithm is used to intelligently diagnose some ECG events, which helps ordinary people understand the ECG waveform more easily and prevent worse heart problems.

Bulky, with wires
Wearing ways
Time of getting ECG Analysis
It costs lots of time. The person has to rent the Holter monitor, record his ECG and physically deliver the data to a cardiac center to be analyzed.
There already have been some studies that compared the arrhythmia-detecting abilities of the classic Holter monitor with that of the new ECG recorder. Those studies showed that a single-lead ECG recorder continuously recording ambulatory ECG is suitable for detecting cardiac arrhythmias in patients referred for dynamic ECG monitoring. The classic Holter monitor is rented from the hospital for limited 24 hours, while the single-lead ECG recorder is bought by the patients and can be used for a longer time. During the first 24 hours, the multi-lead Holter detected more arrhythmia events than the single-lead ECG recorder. However, since patients would not mind wearing the ECG recorder with patches or chest straps for a relatively long period of time, the portable device was able to detect more ECG events than the bulky Holter. Thus you can see the feasibility of Wellue ECG Recorder with AI Analysis. One day, this compact and portable ECG monitor will play a big role in ambulatory ECG monitoring. It is not to replace the Holter and doctor's analysis, but is to help doctors diagnose quicker and help patients know their hearts better so as to prevent the serious condition.

Palpitations, panic, dizziness, shortness of breath ...... Believe that many people have experienced this situation, but you do not know what is happening. Once there is a slight improvement, it will not be a concern of most of them. In fact, we should all be alert to the above symptoms, it may be atrial fibrillation!
AFib is a serious hazard to human health, affecting the quality of life in light cases, and can cause disability and death in serious cases. What are the consequences of atrial fibrillation? And what is the most common treatment for atrial fibrillation? Let's have a simple understanding.
As the saying goes, good comes out of working together. When the heartbeat is not in unison, the cardiovascular system naturally does not work well. It affects the body in two main ways.
The heart acts as a pump, constantly pumping back the venous blood and then pumping out the arterial blood to maintain the blood supply needed by the body. However, if it pumps very quickly, it can only pump a little bit at a time, so the amount of blood that can be pumped out becomes very small. Patients may experience panic and precordial discomfort, and sometimes even fainting, due to the lack of blood supply.
In normal people, the blood flows quietly like a stream, but in patients with atrial fibrillation, it is not so calm. When blood flows through an irregularly fibrillating atrium, it can easily form eddies, which greatly increases the risk of thrombosis. Thrombosis is like sediments of a small stream coalescing into large stones, which will flow to all parts of the body with the blood circulation and block the blood vessels in the corresponding parts.
If the blood clot flows to the blood vessels in the brain, it can lead to brain embolism and cerebral infarction (i.e. ischemic stroke). If the blood clot "runs" to the legs, then it may block the blood vessels in the legs, which can cause ischemic necrosis in serious cases.
There are no drugs that can eradicate atrial fibrillation. Medications can reduce or alleviate atrial fibrillation episodes and keep some patients free of episodes for a significant period of time, but the focal origin of AFib remains and will continue to be present. Therefore, the main goal of drug therapy is to "stabilize" the state.
The incidence of stroke in patients with atrial fibrillation is 3-5 times higher than in the normal population, whether it's paroxysmal AFib or persistent AFib. Anticoagulation is an effective way to prevent strokes. It is also a consistent treatment throughout the whole treatment of atrial fibrillation. Anticoagulation is initiated according to the patient's CHADS2 score (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke).
Anticoagulation must be supervised by a specialist. Excessive anticoagulation may lead to bleeding, while insufficient anticoagulation has no preventive effect.
It is a method of restoring sinus rhythm by using two electrode pads placed in the appropriate part of the patient's chest and distributing an electric current through a defibrillator.
Electrical resuscitation is indicated for: emergency atrial fibrillation (such as myocardial infarction, extremely fast heart rate, hypotension, angina pectoris, heart failure, etc.), atrial fibrillation with severe symptoms that are difficult for the patient to tolerate, atrial fibrillation that was successfully resuscitated last time and has recurred without maintenance with medication.
Electrical cardioversion is not a complete cure for atrial fibrillation. The patient's atrial fibrillation often recurs, and some patients need to continue to take antiarrhythmic drugs to maintain sinus rhythm.
Atrial fibrillation ablation treatment can improve the quality of life. It is suitable for most patients with atrial fibrillation and is less invasive and easily accepted by patients.
Catheter ablation for atrial fibrillation is a technique that has gained popularity in the last 20 years and is a method that can eradicate atrial fibrillation lesions and achieve complete treatment.
Radiofrequency ablation is feasible in patients with symptomatic persistent atrial fibrillation with or without pharmacological treatment.
Currently, it is mainly used for patients with atrial fibrillation who need cardiac surgery due to other heart diseases. The surgery is effective for complete eradication of atrial fibrillation but invasive.
Shall you do radiofrequency ablation or not? Shall you take anticoagulants? All these questions can be safely and boldly thrown to your doctor! All you can do is to pay attention to your ECG report, change your bad habits and actively cooperate with your treatment. By the way, Wellue's 24-hour ECG Recorder with AI Analysis can help you manage your ECG data easier thanks to its highly portability, wireless ambulatory ECG monitoring and effective AI analysis.
What are the symptoms of atrial fibrillation? Why do some people not feel it at all?
Most patients with atrial fibrillation have a fast and irregular ventricular beat. They often feel panic. As fast ventricular beats will lead to a drop in blood pressure, patients will feel dizzy and can even faint. And long-term fast heartbeats can cause heart failure, so patients will have difficulty breathing.
Some patients are not sensitive to irregular heartbeat and often have no symptoms, which can be missed for a long time. Some of them are found during physical examination, such as atrial fibrillation found in the ECG of physical examination after the occurrence of stroke. Or some patients are found to have atrial fibrillation after the occurrence of thromboembolism, such as atrial fibrillation found in the ECG of the hospital examination after lower-extremity arterial thrombosis. Therefore, the symptoms vary greatly from patient to patient.
Common Signs:
Severe Signs:
The symptoms of atrial fibrillation are extremely atypical, so you can't wait until a blood clot forms before you come to the doctor. Then how do you confirm the diagnosis? It is very simple. When you often feel panic and chest discomfort, you need to have an ECG (electrocardiogram). It's convenient and inexpensive. Don't underestimate the sky-like electrocardiogram. After the doctor's analysis, you can find a lot of problems from the ECG.
Routine portable single-lead EKG monitor is hard to detect heart problems for a few moments checking. A Holter monitor can continuously track your heart activity, but it is so bulky to wear as it has many wires.
On the contrary, Wellue® ECG Recorder is not only portable but can also continuously monitor ECG/EKG for 24 hours. In addition, Wellue's FDA-Proved AI ECG platform, which can intelligently diagnose various kinds of abnormal ECG/EKG events, is provided to generate ECG analysis.
Aunt Lala, 66 years old, has suffered from rheumatic mitral stenosis for more than 20 years. Recently, she always felt palpitations, chest pain and shortness of breath. So she went to the hospital to have it checked. The doctor used a stethoscope to hear sounds made by Aunt Lala's heart, and checked her ECG records. Then she was told that it was caused by atrial fibrillation (AFib) and she needs to insist on taking aspirin every day.
What is atrial fibrillation? Why does Aunt Lala need to take aspirin every day?
Today we're going to take a look at those things about atrial fibrillation.
Atrial fibrillation (AFib) is one of the most common clinical arrhythmias. The atria lose their normal effective contraction and are in a state of rapid and disordered fibrillation, with a frequency that can be as fast as 300-600 beats per minute, and a rapid and irregular ventricular beat that can reach 100-200 beats per minute.
In a normal person, the contraction of the atria is a uniform and consistent contraction, similar to the perfect drumming performance, where each drummer is methodically beating the drum in rhythm to produce a strong and powerful sound. However, if the performers are not in the same rhythm, the scene will only be noisy.
Atrial fibrillation can be described as that the heart beats irregularly, similar to the terrible drumming performance. Everyone no longer obeys the command; the heart does not follow the normal rhythm to contract, become fast and irregular. The drums are at best a failure, but if the heart is beating irregularly, the situation is bad.
The type of AFib varies from the episodes of AFib and its response to treatment.
The fibrillating atria must be allowed to beat according to a normal rhythm. You cannot let the fibrillation go on in a disorderly manner but must follow the unified command of the "commander", which is called the sinus node in medical terms. A normal and regular heart rhythm is called sinus rhythm. Medications such as amiodarone can be taken to restore sinus rhythm.
The heart rate has to be slowed down. Medications such as propranolol can be taken to slow the heart rate.
It is critical to prevent thrombosis. Because many patients with atrial fibrillation will have severe cerebral apoplexy and thromboembolism in the future. Thus all patients with atrial fibrillation should be treated with anticoagulation and may take long-term aspirin to prevent thrombosis. That's why aunt Lala needs to take aspirin every day. In addition, depending on the severity of the patient's condition, it is possible that other types of medications (e.g., warfarin) may be required for anticoagulants. This will need to be evaluated in detail by a cardiologist.
Atrial flutter refers to the abnormal electrical conduction pathway in the right atrium, which causes the atrium to beat too fast. The frequency of atrial ectopic pacemakers is 250 ~ 350 beats per minute. Atrial contraction is fast and coordinated, which is tachyarrhythmia between atrial tachycardia and atrial fibrillation. Common in organic heart disease such as rheumatic heart disease, coronary heart disease, hypertension heart disease, cardiomyopathy.
Atrial flutter mainly result from various heart diseases, such as rheumatic heart disease, coronary heart disease, cardiomyopathy, hypertensive heart disease, congenital heart disease and chronic congestive heart failure. Other causes include pulmonary embolism, hyperthyroidism, alcoholism and heart surgery.
The patient's symptoms are mainly related to the duration of atrial flutter and ventricular rate.
Some people have no symptoms at all with atrial flutter. Others describe:
In severe cases, may acute symptoms as below:
Atrial flutter is closely related to AFib, both are atrial arrhythmias.
The differences include:
Take active treatments of diseases that may cause atrial flutter, such as hypertension, coronary heart disease, rheumatic heart valvular disease, hyperthyroidism, etc.
Keep light diets and take more fresh vegetables and fruits. Live in a regular life, prevent overwork and to exercise properly. Most importantly, keeping in good emotion.
To diagnose an atrial flutter or find its cause, doctors usually use tests including:
Some patients can spontaneously restore sinus rhythm in a short time without treatment. If the patient is unable to recover on his own, individualized treatment plans should be developed, which can be treated with antiarrhythmic drugs, and electrical cardioversion or radiofrequency ablation if necessary.

Respiratory sinus arrhythmia is the most common type of sinus arrhythmia. It is more common in children, youth and the elderly, but less common in middle-aged people. The mechanism of respiratory sinus arrhythmia is that the tension of vagus nerve and sympathetic nerve changes during respiration, so that the self-discipline of sinoatrial node changes periodically and regularly.
The pressure receptors in the carotid sinus and aortic arch are stimulated when you inhale, causing the sympathetic nerve to excite, leading to an increased heart rate. When you exhale, it causes vagus tension to increase, resulting in a slow heart rate.
The cycle of heart rate change equaling to a respiratory cycle. The heart rhythm turns neat when you stop breathing. Its ECG/EKG characteristics are as follows:

Most people are confused by their own electrocardiogram, which records a bunch of waveform, which may say "sinus rhythm," "sinus arrhythmia," "sporadic premature beats," and so on. Does such an electrocardiogram mean that your heart is working normally? What is arrhythmia?
We can imagine the heart into a company, the heart rhythm is its work rhythm. The leader of the heart is the sinus node. The sinus node directs the internodal tracts, the atrioventricular bundle(bundle of His), the left and right fascicles, and the Purkinje fiber network to send messages to other parts of the heart. The rhythm triggered by the sinus node, is what we call sinus rhythm, as well as normal rhythm. Arrhythmia occurs when a problem occurs in one part of the heart, preventing the whole body from working properly.
Common arrhythmia include sinus tachycardia, sinus bradycardia, sinus arrhythmia, premature beat, paroxysmal tachycardia, atrial fibrillation, heart block, etc.
According to its occurrence principle, can be divided into abnormal pulse formation and abnormal impulseconduction. According to the heart rate when arrhythmia occurs, can be divided into bradyarrhythmia (heart rate < 50 bpm) and tachyarrhyhmia (heart rate > 100 bpm).
Sinus bradycardia occurs when the sinus node is sick and the command is slow. When the sinus node gets too excited and commands faster, tachycardia occurs. If something wrong with the atrioventricular node, then conduction block occurs. When other departments want to seize the position of the sinus node, it begins to command the subordinate departments, there will be premature beats, atrial fibrillation and other manifestations.
The heart is a blood pumping organ, and abnormal working rhythm will inevitably lead to abnormal blood supply and distribution. Patients may experience symptoms such as palpitation, chest tightness, dizziness, fatigue and even fainting in severe cases. It is suggested to go to the hospital in time if the above symptoms occur.
To diagnose an arrhythmia or find its cause, doctors usually use tests including:
An electrocardiogram records the electrical activity of your heart and be recorded on graph paper. Patients should wear small electrode patches on the chest, arms, and legs for the test. ECG/EKG is the most important noninvasive technique in the diagnosis of arrhythmia, which can determine whether patients have arrhythmia and myocardial ischemia.
This test uses ultrasound to check your heart muscle and valves.
This is a portable EKG (also called an #3d4246"ambulatory electrocardiogram" or an ECG). For regular checkups, a routine ECG/EKG will take just a few minutes, making it difficult to detect heart problems. Wellue ECG Recorder with AI Analysis(24-Hour Holter monitor) can monitor the electrical activity of the heart throughout the day, which is more comprehensive than electrocardiogram and can detect various arrhythmias and other symptoms.
It is important to note that not all arrhythmias need to be treated. In addition to the pathological factors, mental tension, stay up late, too much smoke, wine, strong tea, and coffee also can lead to cardiac arrhythmia.
So, if you find yourself appeared arrhythmia, you should be clear whether you have organic heart disease, such as coronary heart disease, rheumatic, cardiomyopathy, etc. Second, check whether there are correctable triggers, such as myocardial ischemia, electrolyte disturbance, thyroid dysfunction, and then give the corresponding treatment.

Laura was found to have sinus arrhythmia during a recent physical examination. She was very concerned about whether she had a heart attack. Could it be life-threatening?
The first step is to understand how sinus rhythm occurs.
The right atrium has a "commander" that controls the whole heart - the sinus node, which is the point where the normal heartbeat of the human body comes out, and is also the "cardiac pacemaker".
It can automatically, rhythmically send electrical impulses, and then through the heart's special conduction system, successively transmitted to the atrium, ventricle, directing the heart beating. This rhythmic heartbeat, triggered by the sinus node, is what we call sinus rhythm.
If the sinus node releases impulses irregularly, causing uneven contraction of myocardial cells, this phenomenon is sinus arrhythmia reported in our physical examination.
There are many reasons for sinus arrhythmia, and different reasons also cause sinus arrhythmia should be treated by classification.
Common in children and teenagers. Mostly caused by physiological changes, such as tension, emotional excitement, drinking and so on.
This kind of arrhythmia is caused by breathing. The pressure receptors in the carotid sinus and aortic arch are stimulated when you inhale, causing the sympathetic nerve to excite, leading to an increased heart rate. When you exhale, it causes vagus tension to increase, resulting in a slow heart rate.
Many people have high heart rates during physical examinations. Most of the time it is due to excessive tension, or just not calm down after the activity. In fact, there is no need to worry. You can take measurement again after you have calmed down if you’re confused about your result.
What is The Treatment
Sinus arrhythmias are common in children and teenagers. No worry,. They will tend to see their symptoms decrease, as they get older without the need for treatment.
While the exact cause of respiratory sinus arrhythmia is not known, researchers believe Trusted Source it may occur to increase efficiency or allow the heart to do less work while maintaining the correct levels of blood gases.
Most are pathological changes, common in people with other heart disease.
Sinus arrhythmia may occur in patients with coronary heart disease, angina pectoris, rheumatic heart disease, valvular disease, and heart failure.
What is The Treatment
In this case, the key to treatment is not the rhythm of the heart, but the improvement of heart tests. Early diagnosis to exclude myocardial ischemia, myocardial hypertrophy, coronary heart disease and other organic heart disease. Early detection, early treatment.
Sinus arrhythmia is a normal physiological phenomenon if it is not accompanied by organic heart disease. It's not a disease. Usually do not need to take treatment.
Patients always feel anxiety when they're diagnoised to have sinus arrhythmia. They often take wrong treatments because of insufficient understanding of sinus arrhythmia.
The key to preventing sinus arrhythmia is to keep in good emotion. To learn more about Sinus Arrhythmia to reduce excessive worrying that can have mental and physical effects. To exercise properly.
Seeking help from the doctor in time if the symptoms become worse or symptoms such as palpitation, chest tightness, dizziness, fatigue, syncope, angina pectoris occur. We should be alert to the occurrence of pathological sinus syndrome and take further examination to confirm the diagnosis.

Chest tightness, palpitations, shortness of breath... Do these symptoms mean heart disease? How can you test for heart disease?
A Heart disease has become a top killer of human health. Every year, 17 million people died of heart disease, taking up one-third of all deaths worldwide.
In recent years, the increasing incidence of heart disease has seriously affected our physical and mental health. If relevant tests are not performed in a timely manner, it may have seriously bad results and even directly threaten lives.
Therefore, it is especially important to understand the routine detection methods of heart disease to detect heart abnormalities earlier and prevent heart disease.
One himself can detect most of the early symptoms of heart disease, such as a feeling of pressure in the chest, palpitations, shortness of breath and a gray and purple face when doing light exercises. If you find the above symptoms occur frequently, you’d better do some tests to achieve early examination and treatment.
So, are chest tightness, palpitations and breathlessness heart problems? How to confirm the diagnosis in the end?
Let's take a simple look!
Resting electrocardiogram, the most commonly used non-invasive test, can detect a variety of abnormal heart rhythms. This test has a higher detection rate when the patient's symptoms occur. However, if the test is performed during a missed episode, it may show a normal ECG.

Cardiac enzyme testing is one of the most important tools for the diagnosis and differential diagnosis of acute myocardial infarction.
Clinical diagnosis of acute myocardial infarction is based on serial changes in serum enzyme concentrations and elevation of specific isoenzymes.
Currently, coronary angiography is the gold standard for checking cardiovascular health.
It requires an invasive technique to establish a pathway from the patient's femoral or radial artery to the coronary artery. The contrast material is injected into the coronary artery to visualize the main branches of the heart's coronary arteries through the X-ray camera, helping doctors to determine the presence, location, degree, and extent of stenosis in the coronary arteries.
The results of the test are very visual, but it will be more expensive, and at the same time, there is a certain risk as it is an invasive test.
These are the common tests for heart disease, now you know why doctors want you to have so many tests! Remember that the treatment of heart disease is focused on prevention.
Brady Nguyen, a Recreational vehicle service technician, was 55 years old when he noticed dizziness occurring frequently during his work time. One day Mr. Brady told me that he always felt exhausted and that he seemed to climb a mountain when he walked up the stairs.
Mr. Brady went to the hospital to have his condition checked out. His doctor confirmed that he had A-fib, the most common heart rate abnormality. He was advised to take a measurement for his heart in the hospital or at home if his heart was uncomfortable.
During a follow-up inquiry, Brady's primary care physician recommended Wellue's ECG RECORDER WITH AI ANALYSIS, which allows for 24-hour ECG monitoring outside the hospital.
Brady said this product was helpful in his treatment, which was capable to detect arrhythmias and allowed his doctor to diagnose heart abnormalities faster. This product has saved him a lot of time and money, giving him peace of mind.
This product is called ECG RECORDER WITH AI ANALYSIS and is one of the latest ECG products of Wellue to be lanched.
The biggest difference between this product and other ECG monitors is that it can monitor your heart activities continuously for 24 hours and can output a comprehensive data report by powerful AI technique. This is definitely a product that allows you to manage your heart health condition in a timely manner.
The ECG contains a wealth of information about the basic functions and pathology of the heart and reflects the rhythm and electrical activity processes of the heart, so it has a major role and significance in the safety assessment of the heart and the evaluation of various therapies, and is currently the most common and accurate non-invasive means of analyzing and identifying various cardiovascular diseases.
The availability of ECG makes it easier for doctors to diagnose patients' conditions and enables patients to better observe their own heart health.
We have learned that many patients with abnormal heart rates can notice an abnormality in their bodies by themselves and need to see a doctor. Three problems may arise in the process:
- Doctor appointment restrictions
- High medical equipment rental costs
- Hospitals much far from home
As we all know, doctors are not always available at any time. So sometimes patients need to make an appointment before they go to see the doctor, which may cause them to miss the best time for measurement.
For regular checkups, a resting ECG/EKG test takes only a few minutes, making it difficult to detect some heart problems. Since many heart rate abnormalities are episodic, a short-time measurement may not be accurate. This situation requires patients to rent a Holter ECG monitor from the hospital, but hospital-rented ECG testers are often expensive, which is a very heavy burden for most patients. In addition, since the medical equipment is used by a number of people, it is important to pay attention to hygiene and to disinfect and clean it properly.
The third point is that patients may need to travel a long distance from home to the hospital, and each round trip takes a lot of time on the road, which will consume more time and energy.
The Wellue AI Heart Health Monitor lasts up to 72 hours on a single charge, allowing for 24-hour monitoring without missing any abnormalities in the test. The device can store 10 ECG/EKG records for a total of 30 hours. Each ECG/EKG record can last up to 24 hours. And patients can be tested outside the hospital and can easily transmit their test reports to their doctors so as to make quick diagnoses and correct treatment plans, thus better help master their health conditions.
If you are picking a better home heart monitor, you can refer to two criteria: whether the measurement data is accurate and whether the report has details.
- Accuracy level
Many patients worry about the accuracy of the measurement results, how does Wellue AI Heart Health Monitor solve this problem?
Due to the episodic and transient nature of ECG events, the results may vary from measurement to measurement. But this is normal, and Wellue's recommendation is to increase the frequency of monitoring to capture events in a timely manner. The advantages of this AI ECG can be better utilized in this point. And Wellue AI Heart Health Monitor has data with much higher accuracy compared to instant detection devices, by monitoring the heart activities for a long time, at least 24 hours.
- Level of detail
Wellue AI ECG uses AI (artificial intelligence-enabled) ECG algorithms based on 300,000 patients and 50 million learned data segments to analyze the data and generate reports. Intelligent diagnosis of 16 categories and over 104 abnormal ECG/EKG events. Most of the ECG testers on the market just issue a simple report to inform the patient whether it is normal or abnormal. The Wellue AI Heart Health Monitor, on the other hand, has a very detailed test report that gives the patient and doctors more reference data.
On the free PC software, you can view detailed ECG waveforms and reports, including an overview, supraventricular rhythm (8 items), ventricular rhythm (8 items), ECG report conclusions (5 items), and ECG hourly statistics, which are also more informative. Patients can send the test results directly to your doctor, and your doctor can also view detailed data about you, thus faster facilitating their diagnosis and plan treatments.
Traditional portable Holter ECG monitors are full of inconvenience in the process, although they are said to be able to achieve the purpose of monitoring for a long time. The traditional Holter monitor is heavier and requires electrode pads to be attached to various parts of the body, which has many lines wrapped around it. It is more difficult to use and seems very inconvenient when moving around.
The Wellue AI Heart Health Monitor weighs only 0.63 oz/18 grams and can fit anywhere in your pocket. It is very easy to wear or use.
The AI ECG is worn in two ways: with an electrode patch and with a chest strap. With electrode patch wearing, the signal acquisition is resistant to interference. With chest strap wearing, it can be used for a long time and can save your money.
* Holter and AI ECG each can be used in different scenarios. Wellue AI Heart Health Monitor is better in terms of lightness and portability. Patients can make their own choices according to their needs.
Many people worry that using an ECG monitor is too complicated and they won't be able to use it. Wellue AI Heart Health Monitor is designed with this in mind, so we have also configured the automatic on/off function to simplify the testing steps and make it easier to operate. It turns on automatically when worn and stops automatically when taken off. (A flashing green light indicates that the measurement is in progress.) Whether you use it for yourself or give it to your parents and elders, you don't have to worry that they won't use it.

Amazing Advance For those concerned About Cardiac Arrhythmias!
It is much easier to apply than a typical prescribed cardiac monitor. The quality of waveforms recorded is excellent, The user can see that the device is recording properly by seeing the small blinking green light- unlike conventional The report appears quite accurate. Furthermore, the user can quickly jump to any event via a panel on the Furthermore, the user can quickly jump to any event via a panel on the left listing the event (important because a typical recording has over 100,000 beats). The device empowers the user to check results of therapy or type of symptoms as often as desired.
Again, I cannot emphasize how important it is for Wellue to offer this. to my knowledge, there is no similar consumer device. Thank you!
Wellue appreciates your support, join wellue and Power Your Health.
The Olympic Games is a sporting event that affects the hearts of people all over the world, and once again ignited our attention and enthusiasm for sports. Although most of us are not as good as physique and professional level of Olympic athletes, we certainly have sports and fitness habits in our daily lives, and running is a very common one.
When usually run, many of us may only focus on the two data: speed and distance. In fact, these two data are not very important for body fitness.
For ordinary people, comfortable running and slight sweating are the most important health indicators. The word "comfort" is an everyday word that cannot be quantified. While from a scientific point of view, a good heart rate is "comfortable" data performance.
If we want to know what state we are "comfortable" with when running, we must first know a piece of data: the maximum heart rate.
Generally speaking, the maximum heart rate is calculated like this, the formula is 220-your age. For example, if you are 40 years old, then 220-40 is 180 beats per minute. That is to say, a 40-year-old person has a maximum heart rate of 180 bpm. But this is a theoretical value.
Everyone's body is different. Suppose that a 40-year-old fat man and a forty-year-old thin man have completely different heart rates.
Therefore, we need to do an actual measurement of the maximum heart rate. There are three ways to measure the maximum heart rate. The first is the playground mode, running 3 kilometers (7.5 laps in the playground), the second is the climbing mode (400 meters uphill at a slope of 10-15 degrees), and the third is the treadmill mode.
Take the treadmill as an example:
The first step is to run at the most comfortable and easy running (8 kilometers per hour) state, run for ten minutes to warm up, and sweat slightly.
The second step is to run on a treadmill at a speed of 12 kilometers per hour (5:30 seconds pace)
In the third step, each run for 2 minutes, rise 1 degree, continue to rise, do not change the speed.
Of course, running at maximum heart rate is very tiring. It is said that when the measured maximum heart rate value is close to the theoretical maximum value, it may cause vomit. This is a cruel experiment.
Resting heart rate, this concept does not refer to your heart rate when you are sitting in the office and not moving but refers to your lowest heart rate during the morning when you wake up. The purpose of the resting heart rate is to calculate the reserve heart rate, by subtracting the resting heart rate from the maximum heart rate, so that with the reserve heart rate, the heart rate can be used more accurately to monitor the training intensity.
There are two ways to test, the first is to press the pulse of the wrist with your hand for 20 seconds. At the same time, record the number of heartbeats for these 20 seconds, and then ×4, which is your current resting heart rate. The second method is to test with a heart rate monitor. This is relatively accurate and easy.
If an ordinary person does not train, his resting heart rate should be 65 to 75 bpm, but for a long-term aerobic training runner, his heart rate should be below 60 to 50bpm.
American physiologist Camone proposed a reserve heart rate.
Reserve heart rate = maximum heart rate-resting heart rate
This reserve heart rate is generally not needed by everyone, but it is very helpful for training and marathon competitions. Based on the following "training intensity heart rate".
Training intensity heart rate = percentage of target training intensity * (maximum heart rate-resting heart rate) + resting heart rate.
Let us give a few examples:
If you want to do aerobic training and run easily, then the heart rate percentage interval is 59%-74%.
Apply formula:
Training intensity heart rate=59%*(180-60)+60, equal to 130 bpm
Training intensity heart rate=74%*(180-60)+60, equal to 150 bpm
So your aerobic heart rate interval for easy running should be between 130-150bpm.
Many of us wear a sports watch or heart rate belt when running. You can see your heart rate when running this way. However, although wearing a sports watch is sufficient for normal running, it is not enough to be used as professional training such as a marathon. Here we are going to talk about a scientific term called heart rate zone.
According to the above example, the aerobic zone heart rate for easy running is between 130-150bpm.
Then for a marathon, the training intensity heart rate percentage is 74%-84%, and the calculated heart rate interval should be between 150-160bpm.
Running and training are completely different, so you have to adjust them according to your interval.
Your Wellue Strap-free Heart Rate Monitor can be an invaluable tool during training and competition. Happy training!
Some people may say that I have done strength training before and I am in good health. Others will say that I can run a marathon very well... Does the above situation mean that you can increase your training intensity? For example, can you do the interval run?
This involves a concept named heart rate drift rate.
The test method is as follows: run at an easy pace for 90 minutes.
Run at this pace, with a heart rate of A until the tenth minute, continue running for 90 minutes, try to maintain an easy pace (you must drink water during running, but the time of drinking should not exceed 30 seconds). Heart rate after 90 minutes is B.
The formula is (B-A)÷A×100%
For example, you run easily with a heart rate of 130-150 bpm, in the 10th-minute, your heart rate is 126 bpm, if you run at the easy running pace to 90 minutes, your heart rate reached 139 bpm, the calculation result is10%.
As long as this result is less than 10%, it shows that your aerobic foundation is very good. If the result is higher than 10%, you need to strengthen exercise and maintain a healthy body.
In short, although running is a simple sport, scientific quantification can make everyone run healthier.
An electrocardiogram, also known as an ECG/EKG, monitors the number and interval of a test subject's heartbeat and then records the results in a chart. This chart gives a better view of a person's heart health, and if there is a problem with the heart, it will be indicated on the ECG.
The ECG contains a wealth of information about the basic functions and pathology of the heart and reflects the rhythm and electrical activity processes of the heart, so it has a major role and significance in the safety assessment of the heart and the evaluation of various therapies, and is currently the most common and accurate non-invasive means of analyzing and identifying various cardiovascular diseases.
The availability of ECG makes it easier for doctors to diagnose patients' conditions and enables patients to better observe their own heart health.
The simple principle of ECG: ECG is a technique that uses an ECG machine to record the changes in the electrical activity of the heart during each cardiac cycle from the body surface. Therefore, in theory, all diseases that can cause changes in the electrical activity of the heart should be detected by ECG.
What do these technical terms in ECG mean? Next we look together at:
•P wave: Reflects the process of electrical excitation of the left and right atria, also called atrial depolarization wave. The starting point of the P wave indicates the beginning of excitation of the sinus node and the end point indicates the end of excitation of both atria. (Time <0.11 s, amplitude,0.25mv in limb lead, 0.2mv in chest lead)
• P-R interval (Note: different from P-R segment): It indicates the time required for excitation from the sinoatrial node, through the interjunctional conduction bundle, atrioventricular junctional area, and ventricular muscle excitation. (Time 0.12-0.20s)
• QRS wave group: Represents all ventricular myocardial excitation, (time 0.06~0.1s, amplitude, refer to each lead, standard varies from lead to lead)
• S-T segment: Represents the time between the completion of ventricular depolarization and the beginning of repolarization. (normal condition with baseline basic level)
•T wave: Repolarization wave of the ventricle. (generally in the same direction as the main wave)
•U wave: Generally considered to be the repolarization wave of Pope's fiber.
Actually not, it only monitors the electrical signals of the heart by means of ECG sticker electricity, not transmitting any current, so there is no pain. So people who are worried about having an ECG test don't have to worry about painful situations occurring.
You may need to have an ECG test if you have
• Afib heart rhythm abnormalities (arrhythmias)
• If an artery in your heart is blocked or narrowed (coronary artery disease) causing chest pain or a heart attack
• If you have had a heart attack before
• How well certain treatments for heart disease (such as a pacemaker) are working
You may need an electrocardiogram if you have any of the following signs and symptoms.
• dizziness or lightheadedness
• chest tightness
• heart palpitations
• Darkness in the eyes
• Fatigue, weakness or decreased ability to exercise
• Feeling uncomfortable in the heart area
• Conventional ECG Machine
The purpose of rapid ECG testing is the screening and clinical diagnosis of arrhythmias and abnormal ECG waveforms.
Use scenario: mainly used for cardiac examination, physical examination, first consultation of some diseases, routine preoperative examination, etc.
Advantages: the ECG recorded by conventional ECG machine is of the highest quality, mainly in the number of ECG leads is relatively large, generally 12 leads, and the de frequency response range is relatively wide, generally 0.05~150Hz.
Disadvantages: not convenient to carry, use requires the patient to be in a resting state (generally supine), test time is generally less than 10 seconds.
• Vital Signs Monitor
ECG monitor is actually multi-parameter monitoring, because it not only has ECG monitoring, but also pulse wave, oxygen saturation, respiration, blood pressure, and even body temperature monitoring, so it is also called multi-participant monitor.
Use scenario: In the hospital, this equipment is generally needed for monitoring patients in the book, postoperative, postpartum, and critical illness.
Advantage: can monitor a variety of parameters and can continuously monitor.
Disadvantages: not convenient to carry.
• Holter/Protable ECG Monitor
The 24-hour ambulatory ECG recording is performed at home and then brought back to the hospital, where the doctor analyzes it with software to give a report and diagnosis. The quality is between conventional ECG machines and Vital signs monitor, with a frequency response range of 0.5 to 40Hz.
Use scenario: at home, mainly used for ECG monitoring, with less restrictions on the time and place of use
Advantages: it is very convenient for patients to record ECG data freely at home.
Disadvantages: patient activity can still have some effects on the data.
• Compared with heavy ECG meters, Wellue ECG Recorder with AI Analysis is very easy to carry and use, and can be applied to more scenarios: work, home and travel. We can enjoy the convenience brought to you by Protable ECG Monitor, which really achieves to guard your health anytime and anywhere.
• In addition, 24-hour ECG recording can help the doctor screen undiagnosed heart problems and determine how well the treatment is working. Because abnormal heart rhythms may only occur now and then. Monitoring for a longer period of time is necessary to record these events, which helps doctors see why the wearer experiences heart-related symptoms, such as chest pain, shortness of breath, dizziness, fainting...
• Not to be overlooked is the fact that ECGs can be recorded continuously for up to 72 hours per charge, which greatly facilitates our use.
• Wellue ECG Recorder with AI Analysis is also very accurate in terms of measurement data. powerful AI algorithm interprets the recorded ECG, makes it easy for everyone to understand.
• It is important to note that this product allows instant ECG analysis and is free to use. Easily share the data with doctors.
