Radiofrequency Ablation in Frequent Ventricular Ectopy

Abstract

Ventricular premature beats (VPBs) are common findings and occur in broad spectrum of population including subjects with structurally normal hearts and those with cardiac disease, independent of severity. Most of these arise from right ventricular outflow tract and may be asymptomatic or may cause variety of symptoms. High VPB burden is associated with tachycardia induced cardiomyopathy. Symptomatic patients and patients with cardiomyopathy attributable to high VPB burden are offered drugs or catheter ablation. Catheter ablation has high success and low complication rate. Till date VPB frequency and the time point when ablation is recommended is still not clear.
