What are the risks of premature beats?

Premature contractions generally refer to premature contractions. The hazards of premature contractions include cardiac enlargement, angina pectoris, acute myocardial infarction, etc., as follows:

1. If

premature contractions occur frequently, they may cause changes in cardiac structure and function, resulting in cardiac enlargement.

2. When

premature contractions occur in patients with angina pectoris, temporary decrease in cardiac blood flow may lead to myocardial ischemia, causing angina pectoris.

3. Frequent premature contractions of acute myocardial infarction

may cause repeated insufficient cardiac perfusion, resulting in ischemia and necrosis of myocardial cells, thus causing acute myocardial infarction.
