ECGs characteristics of III:1 patient. a Inversion of T wave (V1-V3 leads) in sinus rhythm; Pairs of ventricular premature beat origin from right ventricular tract; cardiac counterclockwise transposition. b Clinical episode of persistent and malignant ventricular tachycardia origin from the inflow-free wall of right ventricle. c–d Ventricular programed stimulation induced short episode of ventricular tachycardia origin from the inflow-free wall (c) and outflow tract of right ventricle (d), during first ablation in the other hospital
