STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? Here is an article I wrote: Updates on the ECG in ACS. The additional ST Elevation in V1 is not usually seen with diffuse subendocardial ischemia, and suggests that something else, like STEMI from LAD occlusion, could be present.

Two recent interventions have proven in randomized trials to improve neurologic survival in cardiac arrest: 1) the combination of the ResQPod and the ResQPump (suction device for compression-decompression CPR -- Lancet 2011 ) and 2) Dual Sequential defibrillation. The patient had ROSC and maintained it.

This suggests diffuse subendocardial ischemia. However, along with that subendocardial ischemia, there is also STE in lead III with reciprocal ST depression in aVL, and some STE in V1. If there is also subendocardial ischemia, the ST depression vector remains leftward, with a reciprocal ST Elevation vector also to the right.

He had a previous MI with cardiac arrest 2 years prior. Down-up T-waves in inferior leads are almost always reciprocal to ischemia in the territory underlying aVL. This is not normal and is a tip off that there is posterior ischemia accompanying the ischemia in aVL. This ECG is diagnostic of ischemia.

If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise. It is prudent to treat the other conditions, get the heart rate controlled, and repeat the ECG.

It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. In a recent article (J Electrocardiol this year, see reference below), peak trop onin I levels in takotsubo presenting with ST Elevation were median 1.02 She was defibrillated and resuscitated. ng/mL [IQR: 0.46, 2.35].

These include ( among others ) — acute febrile illness — variations in autonomic tone — hypothermia — ischemia-infarction — malignant arrhythmias — cardiac arrest — and especially Hyperkalemia.
