Abstract

Background: Identification of an epicardial origin for left ventricular tachycardia (LV-VT) based on electrocardiogram (ECG) criteria facilitates the approach to catheter ablation. Reported criteria, although helpful, may not apply uniformly to all LV regions. Objective: We hypothesized that unique region-specific ECG patterns identify epicardial LV-VTs in patients without myocardial infarction. Methods: The QRS morphologies during pace mapping from 402 epicardial and 234 comparable endocardial sites and 19 epicardial VTs were analyzed in 15 patients with respect to morphology and duration of all and components of the QRS. Results: Basal superior (N = 244) and apical superior (N = 141) pace mapping sites showed Q wave in lead I more commonly from epicardial vs corresponding endocardial sites (90% vs 16%, 88% vs 26% respectively; P
