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). LAFB, atrial flutter, anterolateral STEMI(+) OMI.

This is technically a STEMI, with 1.5 However, I think many practitioners might not see this as a clear STEMI, and would instead call this "borderline." They collected several repeat ECGs at the outside hospital before transport: None of these three ECGs meet STEMI criteria. This ECG was recorded on arrival: What do you think?

This was marked as "Not a STEMI" by the physicians. It is not a STEMI, but it is diagnostic of an LAD OMI (Occlusion MI). has outperformed many cardiologists in its ability to recognize with "high confidence" acute OMIs from ECGs not satisfying STEMI-criteria.

This worried the crew of potential acute coronary syndrome and STEMI was activated pre-hospital. As it currently stands, an ST/S ratio >15% should raise awareness for new anterior STEMI.

You will note that it is essentially an unremarkable electrocardiogram except for some PACS. At baseline, the patient has some expected, normal STE in lead V2, further demonstrating that the STD morphology in the presentation ECG above is "true" and diagnostic. This raised our concerns that the findings on his initial one were real.
