Premature ventricular contractions (PVCs) are common and are considered benign in the absence of structural heart disease. However, high burden of PVCs potentially on 24-hour Holter monitoring, can potentially cause left ventricular dysfunction. In this case, catheter ablation has been demonstrated to be effective at PVC suppression and is associated with improvement or normalization of ventricular function. This form of reversible ventricular dysfunction termed as PVC cardiomyopathy and its pathogenesis is poorly understood at the current time. Rhythmos 2019;14(3):51-54.
