Radiofrequency ablation is useful for treating patients with high frequency of premature ventricular contraction episodes.


Recent studies have shown that those subjects who have an extremely high occurrence of PVCs (several thousand a day) can develop dilated cardiomyopathy. In these cases, if the PVCs are reduced or removed by ablation therapy, the cardiomyopathy usually regresses.[1][2]


  1. Belhassen B (2005), "Radiofrequency ablation of "benign" right ventricular outflow tract extrasystoles: a therapy that has found its disease? In patients with no known coronary artery disease (CAD), the presence of frequent premature ventricular contractions (PVCs) is linked to acute myocardial infarction and sudden death. The Framingham Heart Study defines frequent as >30 PVCs per hour. The American College of Cardiology and the American Heart Association recommend evaluation for CAD in patients who have frequent PVCs and cardiac risk factors, such as hypertension and smoking (SOR C). Evaluation for CAD may include stress testing, echocardiography, and ambulatory rhythm monitoring", J. Am. Coll.
