Can a premature heart beat cause sudden death? Question: Can premature ventricular contractions caus

In most cases, premature cardiac contractions do not cause sudden death, and premature cardiac contractions are divided into atrial and ventricular premature contractions, that is, premature atrial and premature ventricular contractions. In the early stage of the atrial, it generally does not cause more serious arrhythmias, so it does not cause sudden death at all. Ventricular premature is also safe in most states, but the activity of ectopic excitement is increased, and it does not cause more serious arrhythmias, such as ventricular tachycardia and ventricular fibrillation, so it does not cause the problem of sudden cardiac death.

If there are frequent ventricular premature or even multiple ventricular premature, and at the same time there is obvious cardiac enlargement, cardiac insufficiency, or electrolyte problems, blood potassium is very low, this situation will also cause ventricular tachycardia, ventricular fibrillation, or the electrocardiogram problem itself has QT prolongation and other problems, ventricular tachycardia, that is, sudden death

Dr. Chan Chi Kin replied.

This is a common occurrence of this situation for you, so don't worry too much. Premature ventricular contractions can occur in patients with heart disease or in the general population without overt heart disease. It occurs in patients with heart disease, which should be taken seriously and may cause adverse consequences; The risk of sudden death is relatively low in the average person who does not have heart disease, but it must be demonstrated that there is no significant heart disease and that there is no ventricular tachycardia.

It can be seen that in addition to general examinations (including cardiac ultrasound), you must also have some tests (including 24-hour electrocardiogram and myocardial MRI if necessary). In terms of premature ventricular disease without heart disease, drugs are generally used first**, receptor blockers (betalux, Kangxin) are preferred, and other anti-arrhythmic drugs can also be used (such as amiodarone, although these drugs have good effects, they have a certain amount of long-term use, and are not recommended); Secondly, if there is too much premature ventricular contraction (10,000 times for 24 hours), the effect of the drug is limited, and the patient feels that the symptoms are obvious, interventional surgery**, that is, radiofrequency ablation**, and 60-80% of patients will have a significant reduction in premature contractions after surgery, especially in the right ventricular outflow tract. If necessary, you can come to our hospital for treatment.

Happy and healthy!

Premature beat is also known as premature contraction and extramature contraction, referred to as premature contraction. It is an early ectopic heartbeat. According to the origin site, it can be divided into four types: sinus, atrial, atrioventricular junction and ventricular nature.

Among them, ventricular sex is the most common, followed by atrial nature, and premature sinus pulsation is rare. Premature beats are common in ectopic rhythms. Can occur on the basis of sinus or ectopic (such as atrial fibrillation) rhythms.

May be sporadic or frequent, and may occur irregularly or irregularly after every one or more normal beats, forming a dilian or synrhythmic premature beat.

Premature beats may be asymptomatic, or palpitations or pauses may occur. Frequent premature beats can cause symptoms such as fatigue and dizziness (caused by decreased cardiac output), which can induce or worsen angina pectoris or heart failure in people with pre-existing heart disease. Auscultation may reveal irregular heart rhythms with long compensatory breaks after premature beats.

The first heart sound of premature beats is often enhanced, and the second heart sound is often weakened or absent. In a bi- or triad rhythm with premature beats, long pauses may be heard after every two or three beats. Premature beats are inserted between two regular beats and can be seen as three consecutive beats.

Palpation of the pulse may reveal an absence of intermittent pulses.

No, young people have a little arrhythmia, and it's good to have no symptoms, like children generally have sinus arrhythmia. If it's just sinus, don't worry about it, if you don't worry, you can do an ECG a few more times, but if it's over 22, you should pay attention.

Yes, premature cardiac contractions are a manifestation of myocardial ischemia according to TCM diagnosis. Myocardial ischemia can be aggravated by staying up late and overexerting work. Premature contractions occur in mild cases.

In severe cases, chest tightness and chest pain may occur. Dyspnea. Even hypoxic shock may occur.

I want to rely on traditional Chinese medicine to regulate. There is currently no single medicine in Western medicine that can do it**. It can only be temporarily warmed.

Occasional premature beats are not harmful to the human body and will not affect pregnancy and childbirth. Generally, there will be premature beats when you are tired and strenuous exercise, and you should pay attention to rest after premature beats to avoid overwork.

How many premature beats a day? Normal people have premature beats, so the number of premature beats and the location of origin are very important, and it is recommended to improve ECG and 24-hour Holter ECG examination.

Premature contractions, also known as premature contractions and extramature contractions, are a kind of dirty heart beats that occur in advance, and are the most perceptible arrhythmia. It can occur in pathological cases, but premature contractions are more common in the latter, which can come from the atrium, atrioventricular junction ventricles, and are more common in ventricular premature contractions. Occasional occurrences are called occasional premature contractions, and those that occur frequently are referred to as frequent premature contractions.

Vagus nerve excitation can cause atrial premature contractions, while sympathetic nerve excitation can cause ventricular premature contractions. A slow heart rate is more likely to have premature beats than a fast heart rate. Generally speaking, occasional premature beats are of little significance, and are mostly related to excitement, fatigue, full meals, excessive smoking, alcohol, and tea.

Frequent premature beats are often present, and are more common in coronary heart disease, myocarditis, etc. Premature beats at rest or with a slow heart rate are mostly functional, while those that occur during exercise or with a fast heart rate are mostly pathological.

Premature contractions are accompanied by palpitations, palpitations, dizziness, fatigue, insomnia, nervousness, etc., and are easily diagnosed by auscultation or electrocardiogram. However, to determine the frequency and location of premature beats, electrogram is done.

If premature beats occur, do not be nervous, and sedatives can be taken appropriately. Occasional premature contractions are generally not necessary, as long as the triggers listed above are avoided, they can return to normal. Frequent premature beats should be found to be the cause, and the **** should be targeted.

Patients with coronary heart disease should use drugs such as crown dilation and blood stasis; The myocardium is to be antiviral or anti-inflammatory, nourishing the heart, etc.**

Normally, our heartbeats are very regular, like a pendulum, but there are cases where the heartbeat occurs earlier, which is called premature beats.

People may feel palpitation, or have a sense of cardiac pause.

There are many causes of premature contractions, generally speaking, they are divided into functional and organic, the so-called functional refers to the premature contractions that occur without any problems with the heart itself, and the organic refers to the premature beats secondary to other heart diseases (cardiomyopathy, myocardial infarction, coronary heart disease, etc.) If it is a functional premature contraction, that is, you are not very old and have no history of the above diseases, then you can be completely assured that there is no impact on the patient's life and quality of life.

In short, it is not serious.

Be careful not to smoke, drink, or coffee in your life, as these can excite the sympathetic nervous system and aggravate premature beats.

Exercise can be done appropriately, provided that it does not cause symptoms such as palpitation, chest tightness, etc.

Word by word, I hope it will help you, I wish you a good day**.

Hello, your situation indicates that there should be something wrong with your heart, in this case, you must go to the hospital for a cardiac ultrasound examination or 24-hour Holter electrocardiogram examination, according to the situation of the examination, you can make a clear judgment and symptomatic**.

Premature heart beats can cause symptoms such as discomfort in the precordial area, palpitations, palpitations, and restlessness. The specific situation should be determined according to the condition**, you can do an electrocardiogram examination to see what the specific situation is, and choose drugs such as Wenxin granules, betaloclix, and amiodarone according to the examination.

Condition analysis: Premature cardiac beats are generally not life-threatening.

Guidance: Premature heart beats can cause symptoms such as precordial discomfort, palpitations, palpitations, restlessness, etc., which should be determined according to the condition, and an electrocardiogram can be done to see how the specific situation is, and drugs such as Wenxin granules, betalux, and amiodarone can be selected according to the examination.

Disease analysis: premature beats are early heartbeats, which can be seen in normal people and vagus nerve hyperactivity, and can also be seen in myocarditis, coronary heart disease, cardiomyopathy, etc., and sometimes drug influence and electrolyte disorders can also be caused. It can be asymptomatic, or there are palpitations, dizziness, irregular heartbeat, etc., and the occasional ones have no effect on the body, and there is no need to **, and the frequent uncomfortable symptoms are first removed from the triggers, and then the drug can be appropriately applied.

Suggestions: It is best to have a detailed examination, you can do an electrocardiogram, and if there is no positive finding, you can check the 24-hour ECG monitoring. Check whether it is a premature beat, what type it is, whether there is any danger, etc., and then target**, so that the effect is good.
