Ventricular premature beats can occur in the normal population, caused by autonomic nervous dysfunction. These premature beats are not considered heart disease. However, ventricular premature beats caused by certain heart diseases are considered heart disease. Common heart diseases include congenital heart disease, viral myocarditis, rheumatic heart disease, coronary artery disease, and pulmonary heart disease. These diseases lead to myocardial damage and ischemia, causing abnormal conduction rhythms, resulting in premature beats. Treatment should be provided based on different causes, and the premature beats should be corrected simultaneously.
