Wide QRS complex in electrocardiogram is helpful to differentiate ventricular tachycardia from paroxysmal supra ventricular tachycardia (PSVT).

What is the ECG diagnosis? [img=650x131]17de86e2f86d9bc.png[/img] A: Supraventricular tachycardia B: Ventricular tachycardia C: Ventricular fibrillation D: Asystole
