Figure 3: (a) 12-lead surface electrocardiogram of the ventricular tachycardia induced in EP lab. (b) Surface electrocardiogram-leads I, aVF, V1, V6 and intracardiac electrograms – RFD (mapping and ablation distal), RFP (mapping and ablation proximal), his bundle electrogram distal, his bundle electrogram proximal – showing mid diastolic potentials (*) during the ventricular tachycardia with mapping catheter positioned at the posterior wall of right ventricular outflow tract
