The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

When I was shown this ECG, I said it looks like such widespread ischemia that is might be a left main occlusion, or LM ischemia plus circumflex occlusion (high lateral and posterior OMI). Today's patient did make it to the hospital — but was in cardiogenic shock, and despite valiant attempt at treatment, succumbed soon after.
