The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. Hence the first ECG was labeled 'anterior ischemia' based on ST depression, rather than identifying this as reciprocal from posterior OMI. Am J Emerg Med 2016 5. Meyers et al. Herman et al.

ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum. 2016 Sep;68 Suppl 2(Suppl 2):S226-S227. 2016; 6:49-51. Injury current of basal part of septum is directed towards right shoulder and aVR. Indian Heart J. Yamaji H et al.

Computer read: "Non-specific ST abnormality, consider anterior subendocardial ischemia" There are very poor R-waves in V1-V4 suggesting old anterior MI. Firstly, subendocardial ischemia does not localize on 12-Lead ECG. But the real question at hand is: Are these precordial ST-depressions a result of subendocardial 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.
