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. Murakami MM.

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.

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.
