Acute myocardial infarction

Acute myocardial infarction

Acute myocardial infarction refers to a severe form of coronary heart disease caused by acute blockage of the coronary arteries (arteries that supply blood to the heart), leading to ischemic necrosis of a portion of the myocardium. It can often result in serious complications such as arrhythmias, heart failure, and shock, which are life-threatening. The elderly are a high-risk group. The incidence of acute myocardial infarction in China is increasing year by year.

Atrial premature beats

Atrial premature beats

Atrial premature beats, also known as atrial premature contractions, are abnormal atrial beats that originate from an ectopic focus in the atria and are a relatively common type of arrhythmia. Approximately 60% of healthy adults experience atrial premature beats during 24-hour Holter monitoring. They are more common in individuals with organic heart disease and can often trigger other arrhythmias.
