The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

4,5] We have now formally studied this question: Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review.[6] have published a number of warnings about the previous reassuring studies.[4,5]

If we took this as the gold standard, we would conclude that the computer interpretation was safe and accurate at least accurate enough to not miss STEMI, and that physicians should not be interrupted to interpret it, because there would be no change in patient management. What is the gold standard for ECG interpretation: patient outcome!!!

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?

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.

Code STEMI was activated by the ED physician based on the diagnostic ECG for LAD OMI in ventricular paced rhythm. This was several months after the 2022 ACC Guidelines adding modified Sgarbossa criteria as a STEMI equivalent in ventricular paced rhythm). Annals of Emergency Medicine 2021.
