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?

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. New insights into the use of the 12-lead electrocardiogram for diagnosing acute myocardial infarction in the emergency department.

A Deep Neural Network learning algorithm outperforms a conventional algorithm for emergency department electrocardiogram interpretation. But lead V2 has a worrisome amount of ST elevation, and in a chest pain patient, I would be worried about STEMI. I do research on Cardiologs' algorithm: Smith SW et al. What an honor.

The utility of the triage electrocardiogram for the detection of ST-segment elevation myocardial infarction. October 2018. link] In this paper, in a department in which they state they have only 50 STEMI per year, they looked at only 8 days worth of triage ECGs for a total of 538. Am J Emerg Med 36(10):1771-1774. Fair enough.

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?
