I have here 38 cases of "Computer Normal" ECGs which were critically abnormal and the vast majority are missed acute coronary occlusions (Missed Acute OMI) and most were recognized by the physician. Of the Non-STEMI in our cohort, about 25% will actually have acute coronary occlusion. So this study is worthless and must be ignored.

I want all to know that, with the right mind preparation, and the use of the early repol/LAD occlusion formula, extremely subtle coronary occlusion can be detected prospectively, with no other information than the ECG. It is not a missed STEMI, but it is a missed coronary occlusion. Fesmire et al. Wang T, Zhang M, Fu Y, et al.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Author continued : STE in aVR is often due to left main coronary artery obstruction (OR 4.72), and is associated with in-hospital cardiovascular mortality (OR 5.58).

Moreover, the research which appears to confirm this idea was indeed in relation to the circumflex, but they did not study Occlusion ; rather, they studied asymptomatic coronary disease. I showed conclusively that this is a common finding in normal ECGs, though it is more common in LAD Occlusion than in norml variant STE.

This " imbalance of precordial T waves" is not seen very often — and in the “right” clinical setting, has been associated with recent OMI from a LCx culprit artery ( See Manno et al: JACC 1:1213, 1983 — and the July 17, 2013 post by Salim Rezaie in ALiEM ).
