Step 1 to missing posterior MI is relying on the STEMI criteria. A prospective validation of STEMI criteria based on the first ED ECG found it was only 21% sensitive for Occlusion MI, and disproportionately missed inferoposterior OMI.[1] But it is still STEMI negative. A 15 lead ECG was done (below). In a study last year, 14.4%

Notice on the right side of the image how the algorithm correctly measures STE sufficient in V1 and V2 to meet STEMI criteria in a man older than age 40. As most would agree, this ECG shows highly specific findings of anterolateral OMI, even with STEMI criteria in this case. Thus, this is obvious STEMI(+) OMI until proven otherwise.

There’s inferior ST depression which is reciprocal to subtle lateral convex ST elevation, and the precordial T waves are subtly hyperacute – all concerning for STEMI(-)OMI of proximal LAD. There’s ST elevation I/aVL/V2 that meet STEMI criteria. This is obvious STEMI(+)OMI of proximal LAD. Non-STEMI or STEMI(-)OMI?

The limb leads have been removed because there was no ST elevation in those leads, the QRS complexes have been obscured because this is irrelevant to STEMI criteria, and red lines have been added to measure ST segment elevation. But STEMI criteria ignore all this and look at ST segments in isolation.
