Abstract

Background: Usefulness of 12-lead ECG for predicting an epicardial origin for ventricular tachycardia (VT) arising from the right ventricle (RV) has not been assessed. An epicardial approach is sometimes warranted to eliminate RV VT. Objectives: The purpose of this study was investigate the hypothesis that specific ECG features identify an epicardial origin for RV VT. Methods: To mimic an endocardial or epicardial origin, we paced representative sites in 13 patients undergoing RV endocardial/epicardial mapping (134/180 pace map sites). Results: QRS duration from epicardial vs endocardial sites was not different (183 ± 27 ms vs 185 ± 28 ms, P = .3). Reported cut-off values for identifying epicardial left ventricular origin, pseudo-delta wave (≥34 ms), intrinsicoid deflection time (≥85 ms), and RS complex (≥121 ms) did not apply to the RV. A Q wave in lead II, III, or aVF was more likely noted from inferior epicardial vs endocardial sites (53/73 vs 16/43, P 2 was noted from anatomically matched epicardial anterior RV sites (22/33 vs 13/33, P
