This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). The patient improved, and on Day-11 of the hospital stay — he was off inotropes and on a small dose of a ß-blocker. He required multiple defibrillations within a period of a few hours.

His prehospital ECG showed "inferior" ST depression and high voltage, with tachycardia. I suspected no OMI, that this could be due to LVH plus tachycardia. Conclusion: Type II MI probable due to hypoxia and tachycardia from resp arrest and amphetamine use. On arrival to the ED, the patient was diaphoretic, tachycardic.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.
