摘要：
PVCs Induced Mechanical Bradycardia and Cardiomyopathy. Left ventricular (LV) dysfunction due to frequent isolated premature ventricular contractions (PVCs) has been rarely reported. LV dysfunction and concealed mechanical bradycardia resolved in a patient with idiopathic dilated cardiomyopathy after the focal source of PVCs in the LV was eliminated by radiofrequency ablation (RFA). The patient remained free from PVCs and maintained normal LV function over 36-month follow-up. In a subset of patients with idiopathic dilated cardiomyopathy with frequent isolated PVCs, RFA of the arrhythmic focus restores normal LV function that can be long lasting.
