Post Cath ECG: Obviously completing MI with LVA morphology, and STE that meets STEMI criteria (but pt is still diagnosed as "NSTEMI"). Day 12 ECG: FINAL DIAGNOSIS: "NSTEMI" Despite the fact that his day 4 ECG easily meets STEMI criteria, the patient is diagnosed as NSTEMI. No TIMI flow was listed in the report.

A "STEMI alert" was called and soon cancelled. Comment by K EN G RAUER, MD ( 3/1 /2023 ): = Today's case by Dr. Meyers serves as a reminder of the important clinical entity known as diffuse subendocardial ischemia. ST depression will not always be present in 9/12 leads — as is seen in Figure-1.

But these cases show the potential dangers of delayed recognition and treatment of inferior reperfusion Take away 1. Rather than using terms like “STEMI” and “Wellens”, it’s more helpful to describe the underlying pathology and ECG pattern pattern: Occlusion MI, and reperfusion T wave inversion 4.

There is an obvious inferior posterior STEMI(+) OMI. We recorded an ECG in which V1-V3 were put in the position of V4R-V6R, and V4-6 were placed in V7-9 to (academically) confirm posterior OMI. 1 mg of Atropine was given and the heart rate increased transiently to 60. What is the atrial activity? How would one tell? What to do?

There is STE in III and aVF which does not meet STEMI criteria due to insufficient STE in lead aVF. The interventionalists insisted that the ECGs did not meet STEMI criteria and cancelled the activation, stating that they would consider urgent cath after further stabilization. This is an obvious inferoposterior OMI. mm STE with 9.5

It does not meet STEMI criteria. Obvious STEMI(+) OMI of inferior, posterior, and lateral walls, now with likely 2nd degree heart block type 1 (Wenckebach). Learning Points: We can find OMI on ECG much sooner than STEMI criteria in many cases, and of course many OMIs never meet STEMI criteria at all.

The pattern of STE and STD reminded us of Brugada Type 1 morphology. Smith comment: 1) Brugada ECG may have ST shifts in limb leads as well as precordial leads. 2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. per year incidence of SCD in this cohort [1].

Despite the clinical context, Cardiology was consulted due to concerns for a "STEMI". Hyperkalemia mimics STEMI and OMI in many distributions, but probably the most common is the Brugada morphology in V1-V2 which mimics anterior OMI for those who cannot recognize the Brugada pattern. Limb lead reversal can be easily recognized.

Not quite a STEMI, but same effect.) There is ST elevation in V2-V4 that does not quite meet "STEMI criteria." That is a reasonable thought, but we have shown that if there is one lead of V1-V4 with a T/QRS ratio greater than 0.36, then it is STEMI, not LV aneurysm. Is this a transient STEMI? Learning Points: 1.
