[Drug treatment of chronic ventricular arrhythmia]

Abstract

The treatment of chronic ventricular arrhythmias depends on the severity and tolerance of the arrhythmia. Extrasystoles, even repetitive, in the healthy heart, are usually respected when asymptomatic or treated with betablockers in first intention when symptomatic. These drugs should also be proposed for patients with ischemic heart disease and non-sustained ventricular tachycardia, a situation in which Class I antiarrhythmics should be avoided. The prevention of sustained ventricular tachycardial may be empirical, with betablockers and/or amiodarone, or guided by the results of pharmacological tests during endocavitary electrophysiological studies.
