Idiopathic Left Ventricular Tachycardia: What Is New in Pathophysiology? When and How to Perform RF Ablation?

  • R. Cappato

Abstract

In 1979, Zipes et al. [11 reported about a peculiar category of ventricular tachycardia characterized by a QRS 0.12 to 0.14 s long, a right bundle branch block configuration and a left deviation of the electrical axis. Further reports have confirmed that this arrhythmia occurs in individuals who are otherwise healthy (idiopathic, I) and originates from the postero-inferior left ventricular septum (left ventricular tachycardia, LVT), as postulated by Zipes et al. [1]; in addition, the modality of onset during programmed electrical stimulation as well as the response to pharmacologic agents have suggested that the mechanism that is most probably responsible for ILVT is reentry [2].
