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.

Cardiac arrest can cause diffuse subendocardial ischemia, usually transient (it often resolves as time goes by after ROSC). An echocardiogram on day 3 showed no wall motion abnormality (but of course, these can resolved with reperfusion, and the more time it has to resolve from "stunning", the more likely it is to be resolved).

An echocardiogram confirmed aortic stenosis with a large pressure gradient. Now there is much less ST segment deviation, less elevation and less depression. The troponin returned positive, and the maximum troponin was 3.8 The next day, and angiogram showed normal coronary arteries. He awoke and did well.

Category 2 : An increase in myocardial oxygen demand due to tachycardia, elevated ventricular afterload (BP or aortic stenosis), or increased wall stretch (admittedly this latter is more complicated) or a decrease in oxygen supply due to hypotension, anemia, hypoxia, or a combination of all of the above.

History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. See this case: what do you think the echocardiogram shows in this case? 2 cases of Aortic Stenosis: Diffuse Subendocardial Ischemia on the ECG. His response: “subendocardial ischemia.

It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. Here is the cath report: Echocardiogram: There is severe hypokinesis of entire LV apex and apical segment of all the walls. She was defibrillated and resuscitated. I need to innoculate you against the subsequent opinions below.
