A man in his 70s with acute chest pain and paced rhythm.

Code STEMI was activated by the ED physician based on the diagnostic ECG for LAD OMI in ventricular paced rhythm. This was several months after the 2022 ACC Guidelines adding modified Sgarbossa criteria as a STEMI equivalent in ventricular paced rhythm). LAFB, atrial flutter, anterolateral STEMI(+) OMI.

90 year old with acute chest and epigastric pain, and diffuse ST depression with reciprocal STE in aVR: activate the cath lab?

Dr. Smith's ECG Blog

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

A man in his early 40s with chest pain a "normal ECG" by computer algorithm. Should we avoid interrupting a physician to interpret his ECG?

Dr. Smith's ECG Blog

Notice on the right side of the image how the algorithm correctly measures STE sufficient in V1 and V2 to meet STEMI criteria in a man older than age 40. As most would agree, this ECG shows highly specific findings of anterolateral OMI, even with STEMI criteria in this case. Thus, this is obvious STEMI(+) OMI until proven otherwise.

How does Acute Total Left Main Coronary occlusion present on the ECG?

Dr. Smith's ECG Blog

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

Right precordial ST depression in a patient with chest pain

Dr. Smith's ECG Blog

The precordial ST-depression pattern on this ECG (and in this clinical setting) should immediately raise suspicion of Posterior STEMI! Posterior STEMI occurs in approximately 15-20% of acute MI, but the vast majority of the time it is seen in conjunction with inferior (Infero-Posterior) or lateral (Postero-Lateral) STEMI (1).

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center.

Hyperthermia and ST Elevation

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.
