Mapping of Idiopathic Ventricular Tachycardia. Idiopathic left ventricular tachycardia with a right bundle, left‐axis deviation is thought to originate from posterior fascicles. Recently, there has been considerable interest in the anatomic and mechanistic basis of this arrhythmia. We report our experience with a 26‐year‐old man in whom new noncontact mapping technology was used to acquire detailed data from the left ventricle, identify the mid‐diastolic potential and part of the ventricular tachycardia circuit, and perform successful ablation. This information helped define the physiologic aspects of this unique tachycardia.
