The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

First, many on Twitter said "Pericarditis". This is NOT pericarditis, which virtually NEVER has ST depression any where except aVR. See our publication: ST depression in lead aVL differentiates inferior ST-elevation myocardial infarction from pericarditis There is STE in inferior leads, high lateral leads, and V4-V6.

This is a bad ST vector orientation, because it causes widespread STE and one of the most important mistakes that needs to be avoided here is thinking of the diagnosis of pericarditis. Such an out-of-proportion STE is virtually never seen in pericarditis. 2021 Sep;49(6):488-500. Look at the STE in lead II, aVF. 2021.21026.

The limb leads have been removed because there was no ST elevation in those leads, the QRS complexes have been obscured because this is irrelevant to STEMI criteria, and red lines have been added to measure ST segment elevation. But STEMI criteria ignore all this and look at ST segments in isolation.
