Post cath ECG: Now there are hyperacute T-waves again, and recurrent ST depression in V2 This ECG would normally diagnostic of OMI until proven otherwise No further troponins were measured, but it looks like there is recurrent OMI Next day: A CT Coronary Angiogram was done (CTCA) CARDIAC MORPHOLOGY AND FUNCTION: 1. IMPRESSION: 1.

This EKG is diagnostic of transmural ischemia of the inferior wall. If it is angina, lowering the BP with IV Nitroglycerine may completely alleviate the pain and the (unseen) ECG ischemia. Transmural ischemia (as seen with the OMI findings on ECG) is not very common with demand ischemia, but is possible. Smith SW.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

It should be known that each category can easily manifest the generic subendocardial ischemia pattern. In general, subendocardial ischemia is a consequence of global supply-demand mismatch that usually ameliorates upon addressing, and mitigating, the underlying cause. What’s interesting is that the ECG can only detect ischemia.

When “spot diagnosing” precordial ST-depression I instinctively evaluate aVR for any corresponding ST-elevation to see if an emerging pattern of broad subendocardial ischemia can be appreciated, in which the ST-depression should be otherwise global and demonstrably maximal in Leads II and V5. ST-elevation, etc.) is present. 1] Driver, B.

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?

There is broad subendocardial ischemia as demonstrated by STE aVR with concomitant STD that almost appears appropriately maximal in Leads II and V5. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. This worried the crew of potential acute coronary syndrome and STEMI was activated pre-hospital.
