The beating of a normal heart is regular, and the interval between heartbeats is basically equal. If there is a sudden premature beat, it is medically called premature beat (premature beat), or premature beat. Premature beats are caused by excessive excitement of a certain part of the heart. If there is premature beat caused by atrial overexcitation, it is called atrial premature beat. If there is a high point of excitement in the atrioventricular node or ventricle, it is called atrioventricular node or ventricular premature beat. When measuring the pulse, there may be an early jump or a "missed jump". It can be distinguished by ECG examination. According to the frequency of premature beats, more than 6 beats per minute are called frequent premature beats, and less than 6 beats are accidental premature beats. If premature beats appear in pairs, it is called dichotomy; If three appear in groups of three, it's called the dichotomy.

Premature beats are common in normal people.

If normal people observe ECG continuously for 24 hours, 70 ~ 80% may record premature beats. Although premature beats are irregular beats of the heart, they are not all caused by diseases. Emotional tension, excitement, anxiety, excessive smoking, heavy drinking, strong tea and even constipation can all cause premature beats. But most people have no discomfort, or just feel a little heart swing, or 1 beat, or heart twitch. Frequent premature beats often make people feel flustered, chest tightness, fatigue and other discomfort.

Many diseases can lead to premature beats.

Such as hyperthyroidism, anemia, hypokalemia, fever and other non-heart diseases, premature beats will occur. Of course, all kinds of heart diseases can cause premature beats, but premature beats are more common in rheumatic heart disease, coronary heart disease, myocarditis, cardiomyopathy and other heart diseases. Frequent premature beats occur on the basis of severe heart disease, and even cause angina pectoris or heart failure.

What if I find premature beats?

1. Don't be too nervous when premature beats occur. Ask the doctor to further examine the causes of premature beats and evaluate the severity of premature beats. If the causes of premature beats can be found, as long as the causes of premature beats are removed and the diseases that induce premature beats are cured, premature beats can be gradually eliminated. If the cause of premature beats cannot be found, please ask the doctor to decide whether it is necessary to treat premature beats. Most patients with premature beats have a good prognosis.

2. Occasional premature beats have little effect on blood circulation, especially if they are not caused by other diseases. Premature beat itself is not a very serious disease and generally does not need treatment. Therefore, patients should eliminate their worries and remain optimistic.

3. Frequent premature beats, especially those that may develop into serious arrhythmia on the basis of heart disease, or may lead to angina pectoris and heart failure, should be paid attention to. There are many drugs to relieve premature beats, such as propranolol, isosorbide dinitrate, bradycardia, amiodarone, quinidine and procainamide. These drugs are more violent and should be taken under the guidance of a doctor. Be patient in treatment and don't change medicine frequently. After the premature beats are controlled, a small amount of drugs are still needed to avoid the recurrence of the disease.

If the drug treatment is ineffective, patients can't tolerate it, or have frequent premature beats with a certain degree of malignancy, radiofrequency ablation can be used, and some patients can be cured.

It may have been a long time ago for the frequent unexplained premature beats. Many patients are used to it, and if the doctor evaluates it as benign, there is no need for treatment.

4. Don't smoke, drink, overeat and eat less irritating food. Pay attention to the combination of work and rest and get enough sleep. Chronic patients with no increase in premature beats after exercise should participate in cultural and sports activities appropriately.
