Cath lab declined as it is not a STEMI." There is probably a trickle of flow which is why there is both subendocardial ischemia (ST depression) and early subepicardial ischemia (hyperacute T-waves). And now this finding is even formally endorsed as a "STEMI equivalent" in the 2022 ACC guidelines!!! It is a mass delusion.

This was a machine read STEMI positive OMI. In this patient's case, the RV ischemia manifested as dramatic anterior hyperacute T waves. This degree of STE is a bit atypical for LAD ischemia. Written by Willy Frick A 50 year old man with no medical history presented with acute onset substernal chest pain. His ECG is shown below.

This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. This rules out subendocardial ischemia and is diagnostic of posterior OMI. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later?

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished.

V1 sits over both the RV and the septum, so transmural ischemia of either one with give OMI pattern in V1 and reciprocal STD in V5 and V6. See this post: Septal STEMI with ST elevation in V1 and V4R, and reciprocal ST depression in V5, V6. However, the pattern is also seen in inferior OMI with right ventricular OMI. (V1

Post Cath ECG: Obviously completing MI with LVA morphology, and STE that meets STEMI criteria (but pt is still diagnosed as "NSTEMI"). Smith : the profound persistent STE suggests either persistent occlusion or " no reflow " with persistent downstream ischemia. Academic Emergency Medicine 27(S1): S220; May 2020. Abstract 556.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. There is no definite evidence of acute ischemia. (ie, Distinction of PMVT vs VFib is an academic one in this case ). Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. (
