Ventricular Premature Beats Originated from the Posterior Cardiac Vein

A 60-year-old male suffered from dyspnea on effort. He had a ventricular premature beats (VPCs) with QRS complex of right bundle branch morphology and superior axis, which resulting in a poor left ventricular function. The origin of these VPCs was the epicardium of left ventricular along the posterior cardiac vein. A Radiofrequency current delivery applied at that vein eliminated VPCs. He remained free of any arrhythmias after the procedure, and his left ventricular function was increasing.
