"Non-STEMI" is a worthless term.

Dr. Smith's ECG Blog

A 60 yo with 2 previous inferior (RCA) STEMIs, stented, called 911 for one hour of chest pain. Here is his most recent previous ECG: This was recorded after intervention for inferior STEMI (with massive ST Elevation, see below), and shows inferior Q-waves with T-wave inversion typical of completed inferior OMI. ng/mL (quite large).

Takotsubo Stress Cardiomyopathy, with Echocardiogram

In this case, the ECG never mimicked a STEMI. I will proceed to post a couple cases in which SCM does mimic STEMI.

Tachycardia must make you doubt an ACS or STEMI diagnosis; put it all in clinical context

Dr. Smith's ECG Blog

He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. At first glance, it seems the patient is having a STEMI. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock.

What do you think the echocardiogram shows in this case?

Dr. Smith's ECG Blog

What do you think the echocardiogram shows? There is a subtle but important difference between OMI and subendocardial ischemia: OMI (that is not STEMI) is due to TIMI 0/1 flow and has any combination of subtle STE, hyperacute T-waves, reciprocal ST depression, decreased QRS amplitude, terminal QRS distortion and other findings.

Transient STEMI, serial ECGs prehospital to hospital, all troponins negative (less than 0.04 ng/ml)

Dr. Smith's ECG Blog

This is a 45 yo male who had an inferior STEMI 6 months prior, was found to have severe LAD and left main disease, and was supposed to be set up for CABG a few weeks later, but did not follow up. But it could be anterior STEMI. 40% of anterior STEMI has upward concavity in all of leads V2-V6. is likely anterior STEMI).

Large Transmural STEMI with Myocardial "Rupture" of Ventricular Septum

Dr. Smith's ECG Blog

Thus, this is both an anterior and inferior STEMI. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. Armstrong et al.)], the presence of such well developed anterior Q-wave suggests completed transmural STEMI. Could it be acute (vs.

See OMI vs. STEMI philosophy in action

Dr. Smith's ECG Blog

He visited an outpatient clinic for it and an echocardiogram and exercise stress test was normal. In the meantime, cardiology consultant sees the patient and performs a bedside echocardiogram which revealed no major wall motion abnormalities. Take home messages: 1- In STEMI/NSTEMI paradigm you search for STE on ECG. 2021.21026.
