Abstract

We describe a case of idiopathic left ventricular tachycardia in which the left posterior fascicle was clearly delineated to be a bystander in a re-entry circuit, with participation of the left interventricular myocardium as the retrograde limb instead. To the best of our knowledge, this is the first case report that has directly proven the left posterior fascicle to be a bystander during idiopathic left ventricular tachycardia.
