link] A 62 year old man with a history of hypertension, type 2 diabetes mellitus, and carotid artery stenosis called 911 at 9:30 in the morning with complaint of chest pain. Challenge QUESTION: The relative change in T-QRS-D is not the only thing that changes during period of time that passed between recording of the 2 ECGs shown in Figure-1.

A 40-something male presented with dyspnea and left arm numbness, and perhaps some chest tightness, for 1 1/2 hours. This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. You can see the deficiency of the definition of MI. E CG # 1 = the initial Triage ECG ( TOP ) — As per Dr.

Post cath ECG: Now there are hyperacute T-waves again, and recurrent ST depression in V2 This ECG would normally diagnostic of OMI until proven otherwise No further troponins were measured, but it looks like there is recurrent OMI Next day: A CT Coronary Angiogram was done (CTCA) CARDIAC MORPHOLOGY AND FUNCTION: 1. IMPRESSION: 1.

He had episodes of chest pain off and on all night, until about 1 hour prior to arrival when the pain became constant, crushing, 10/10 chest pain that radiated to both arms. Barely any STE, and thus not meeting STEMI criteria. Only now that the patient has STEMI criteria is he allowed to go to the cath lab, at around 0530.

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.

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?
