Localization of Ventricular Arrhythmias for Catheter Ablation: The Role of Surface Electrocardiogram

Card Electrophysiol Clin. 2018 Jun;10(2):333-354. doi: 10.1016/j.ccep.2018.02.006.

Abstract

The surface ECG is a valuable mapping tool in patients with idiopathic and scar-related ventricular arrhythmias (VAs). A detailed analysis of 12-lead ECG can provide useful information in localizing the VA site of origin. This might help tailoring the ablation strategy to optimize procedural duration, increase the probability of success, and prevent complications. The aim of this article is to review the ECG features of both idiopathic and scar-related VAs and discuss their potential implications for optimizing the ablation strategy.
