Demonstration of posterior fascicle to myocardial conduction block during ablation of idiopathic left ventricular tachycardia: An electrophysiological predictor of long-term success

Distal posterior fascicle and Purkinje-myocardial junction is an effective target site for ILVT ablation. The demonstration of myocardial to fascicle conduction block serves as an important electrophysiological marker of successful ablation and improved long-term success.
