What is the cause of premature beats

Premature contraction of the heart generally refers to premature contraction, usually due to excessive pressure, hypertension, myocarditis and other reasons, the specific analysis is as follows:

1. Excessive pressure

If the patient's long-term pressure is too large, it will lead to the blood circulation of the heart being affected, thus causing premature contraction.

2. Hypertension

If the patient has high blood pressure for a long time, it will lead to excessive burden on the left ventricle, causing degeneration of the left ventricular myocardium, leading to expansion of the cardiac chamber structure, resulting in premature contraction.

3. Myocarditis

If the patient has myocarditis, it is due to insufficient blood supply to the heart, resulting in cardiac ischemia and hypoxia, thus causing premature contraction.
