Magnetic navigation in left-sided AV reentrant tachycardias: preliminary results of a retrograde approach.

abstract：INTRODUCTION:Idiopathic left ventricular tachycardia typically has a right bundle branch block configuration. The purpose of this case report is to demonstrate that idiopathic ventricular tachycardia arising in or near the left posterior fascicle also may have a left bundle branch block configuration.
