Premature beats are very common and are classified as physiological or pathological. Some people become cautious when they find out that they have premature contractions and even interrupt their year-round workout routine as a result. Are premature beats really a “no-go” area for fitness? The normal heartbeat is regular and the intervals between heartbeats are basically equal. If there is a sudden advance in the heartbeat, it is called premature beat, or premature beat. Symptoms of premature beats: 1. Irregular heartbeat The human heartbeat is as regular as a musical beat, even if the heart rate is fast or slow, the interval between each heartbeat is approximately the same. However, in some special cases, the regularity of the heartbeat changes, and sometimes the heartbeat occurs earlier, just like a beat rush, which is called premature beats. Premature beats can be asymptomatic and found by chance on physical examination, or they can be accompanied by severe palpitations, chest tightness, and other discomforts. A common symptom of premature beats is a feeling that the heart has suddenly stopped or is empty, sometimes with a “thump” or pain. In severe cases, you may experience shortness of breath or even a lack of energy. 2.Inconsistent pulse The pulse is the fluctuating sensation caused by the heart contraction and the ejection of blood into the arterial blood vessels. When you have the above symptoms, you can feel your pulse immediately. If you feel the pulse when it feels untidy, misses a beat or beats early, then you have premature beats. If you are used to using a stethoscope, you can listen to the rhythm of your heartbeat, which is easier to determine premature beats or other arrhythmias than feeling your pulse. The difference between physiological and pathological premature beats Premature beats are very common in normal people, and if an ECG is used to continuously observe a normal person for 24 hours, it is possible to record 70 to 80% of premature beats. Premature beats can be caused by emotional stress, excitement, anxiety, excessive smoking, heavy alcohol consumption, strong tea, or even constipation. Many diseases can also cause premature beats, such as hyperthyroidism, anemia, hypokalemia, fever, and other non-cardiac diseases. Various heart diseases can also cause premature beats, such as rheumatic heart disease, coronary arteriosclerosis, hypertension, myocarditis and cardiomyopathy. Physiological premature beats are usually risk-free and do not affect people too much; most patients with pathological premature beats have a good prognosis after treatment, but only a few patients with serious underlying cardiac diseases or ionic disorders can induce ventricular tachycardia, ventricular fibrillation, and in severe cases, sudden cardiac death, especially in patients with acute myocardial infarction from coronary heart disease. (Only a few cases) Can patients with premature beats exercise or not? It has been reported in the literature that thousands of people with normal heart function were followed up with 24-hour ambulatory electrocardiograms and it was found that most of them had several premature beats without feeling them themselves. However, once they were told, some people really felt the discomfort of a “hovering” heart. Patients with premature beats are perfectly capable of exercising normally. Physiological premature beats caused by overexertion, strong alcohol, tea, or certain drugs will disappear if the cause is removed. In addition, for premature beats caused by increased excitability of the vagus nerve, which makes the low pacing point of the heart less than normal, they will disappear as long as the sympathetic nerve is excited. So, should a patient with true organic heart disease with premature beats be completely bedridden and say goodbye to exercise from now on? A foreign study selected 28 patients with coronary artery disease who had undergone surgery and adopted a comprehensive health care method of vegetarian diet plus jogging for one hour every day. After one year, these patients had significantly less angina and premature beats. It can be seen that premature beats are not a “no-go” area for fitness exercise, even if they are caused by organic heart disease, they are not completely contraindicated, but of course, pathological premature beats are a disease after all, they should be safe fitness under the premise of experienced specialist to identify the cause, location and nature of premature beats.
