Whether or not premature beats after exercise are life-threatening needs to be determined according to individual differences, disease conditions, etc. If they are rare, they are generally not life-threatening. If it is occasional premature beats, the number is very small, and there is no other disease, generally will not be life-threatening; if frequent ventricular premature beats, combined with myocardial infarction and other cardiovascular diseases, over-exercise may cause malignant arrhythmia, which will be life-threatening.
1. No danger to life: Exercise will speed up the heart rate, if it is occasional premature beats, the number of premature beats is very small, and there is no other heart disease, cerebrovascular disease, etc., generally no matter whether it is atrial premature beats or ventricular premature beats, it will not be life-threatening, and after resting, the heart rate can be restored to normal.
2. Dangerous to life: Exercise speeds up the heart rate, increases the burden on the heart, and can aggravate the original premature beats. If the patient has frequent ventricular premature beats, with a large number of beats, and combined with angina pectoris, myocardial infarction and other cardiovascular diseases, the patient may easily be over-exercised and cause malignant arrhythmia, such as ventricular fibrillation, ventricular tachycardia, which can be life-threatening.
If the patient has premature beats, it is recommended to decide the amount of exercise under the evaluation of the doctor, or if the patient with premature beats has panic attacks, sweating, fainting and other discomforts after exercise, it is recommended to go to the hospital in time.
