An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

While the initial impression might not immediately suggest ventricular tachycardia (VT), a closer examination raises suspicion. Additionally, the qR morphology, particularly in a patient with right bundle branch block (RBBB) type wide QRS complex tachycardia (WQCT), lends further support for VT. What is the rhythm?

This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There is no definite evidence of acute ischemia. (ie, Some residual ischemia in the infarct border might still be present.

There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). This patient was having recurrent episodes of polymorphic ventricular tachycardia with an underlying long QT interval ( = Torsades des Pointes ). ECG #2 Interpretation of ECG #2: Underlying sinus rhythm.

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.
