The electrocardiogram (ECG) revealed a wide QRS complex tachycardia with left bundle branch block-like morphology and atrioventricular dissociation (lead II) (Figure 1), fitting with a ventricular tachycardia (VT) with a midseptal left-ventricular (LV) exit.
Electrocardiogram After Electrical Cardioversion. Pathological inferior Q-waves with convex ST-segment elevations and T-wave negativity in leads V5 to V6.
