Each ventricular tachycardia (VT) morphology, electrophysiological study, and ablation point. A, B: The left sections show morphologies of surface 12-lead electrograms and local intracardiac electrograms during pace mapping at sites A and B, respectively. The right sections show VT 1 and VT 2 morphologies, respectively, on surface 12-lead electrograms. C: Twelve-lead electrograms and local intracardiac electrograms during entrainment pacing at site C during VT 3. D: Ablation points in right anterior oblique (RAO) view (top image) and in caudal view (bottom image). Red tags indicate ablation points.
