Premature beats of more than 20,000 times are more serious. Generally, premature beats of more than 5 times a minute are considered to be frequent premature beats. Most of them are caused by organic diseases, such as myocardial infarction or myocarditis, heart failure, dilated cardiomyopathy, hypertrophic cardiomyopathy, etc. Patients with these types of premature beats must be sure to identify the type of premature beats and, if necessary, opt for radiofrequency ablation surgery for treatment. And some multi-source premature beats may be treated mainly by treating the primary disease while applying drugs to improve the premature beats. Severe episodes of premature beats may induce ventricular tachycardia or other types of arrhythmias, etc. Patients should standardize the treatment.
