ECG showed normal sinus rhythm and ST elevation in leads V1 to V6 with deep Q waves in the same leads (Figure 1).

Then, 2 hours later, he was found unresponsive with pulseless ventricular tachycardia, and after a single DC shock, he regained his consciousness and his sinus rhythm again (Figure 2).
Multiple PVCs and NSVT.

The next morning, he developed asymptomatic sustained ventricular tachycardia that reverted spontaneously to sinus rhythm; then, the telemetry showed multiple premature ventricular complexes (PVCs) and nonsustained ventricular tachycardia (NSVT) (Figure 3).
Ventricular tachycardia.

In the evening, he had ventricular tachycardia (Figure 4) with hypotension, so the situation required the suppression of the arrhythmia by a DC shock, endotracheal intubation, and sedation (midazolam 0.1 mg/kg/hour).
Ventricular tachycardia preceded by PVCs.

The next day, clusters of ventricular tachycardia triggered by ventricular premature contractions occurred (Figure 5) and required multiple electrical defibrillations.
Ventricular paced rhythm at rate of 100.

After another 24 hours of stable rhythm, the pacemaker was removed and close observation showed no any ventricular arrhythmias (Figure 7).
