Radiofrequency Catheter Ablation of Idiopathic Ventricular Tachycardia Originating in the Anterior Fascicle of the Left Bundle Branch

Abstract

Idiopathic VT originating in or close to the anterior fascicle was cured by RF ablation. A Purkinje potential preceding the QRS during tachycardia and an optimal pacemap were used to guide RF ablation.
