Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. The ECG does not show any signs of ischemia. True Positive ECG#2 : Also sinus rhythm. There is ST depression in V1.

Mechanism is thought to be due to sustained sympathetic stimulation, probably caused by dysfunction of insular cortex resulting in reversible neurogenic damage to the myocardium which could include contraction bands and subendocardial ischemia [2]. 2012 Dec;7(4):290-4. 2012 Dec;7(4):290-4.

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 ).

Here was the ECG: There is sinus tachycardia. Our chief of cardiology, Gautam Shroff, interprets it differently and thinks this is indeed ischemia. 109 (20):361-368, 2012 — CLICK HERE ).

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. She was ventilated by bag-valve-mask by EMS on arrival and was quickly intubated with etomidate and succinylcholine. A rectal temperature was obtained which read 107.9

There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. Here is a similar case: Collapse, Ventricular Tachycardia, Cardioverted, Comatose on Arrival. Agitation, Confusion, and Unusual Wide Complex Tachycardia. There is sinus tachycardia at ~115/minute.
