ST depression is common BOTH after resuscitation from cardiac arrest and during atrial fib with RVR. Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiac arrest, after defibrillation, and after cardioversion. The patient was cardioverted. This was done.

The last section is a detailed discussion of the research on aVR in both STEMI and NonSTEMI. 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. Here is an article I wrote: Updates on the ECG in ACS. see below).

An echocardiogram confirmed aortic stenosis with a large pressure gradient. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. The next day, and angiogram showed normal coronary arteries. He awoke and did well.

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. Formal Echocardiogram: Normal left ventricular size and wall thickness.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. See this case: what do you think the echocardiogram shows in this case?

Technically, the STE meets STEMI criteria because there is greater than 2.5 These kinds of cases were excluded from the study as obvious anterior STEMI. mm) Although this was indeed a case of early repolarization, it could be STEMI. In any case, the patient needs at a minimum serial ECGs and perhaps a formal echocardiogram.

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. Formal echocardiogram showed normal EF, no wall motion abnormalities, no pericardial effusion. So maybe she is better than I am. No more troponins were done.
