Below is the first ECG, signed off by the over-reading cardiologist agreeing with the computer interpretation: ST elevation, consider early repolarization, pericarditis, or injury. Theres ST elevation in V3-4 which meets STEMI criteria, which could be present in either early repolarization, pericarditis or injury.

The emergency medicine physician documented, "His initial EKG is riddled with artifact and difficult to interpret but does not look like a STEMI." The ECG remains positive for STEMI by GE. The absolute degree of ST elevation (although enough to meet STEMI criteria), was still relatively small.

.: 50% of LAD STEMI have Q-waves by one hour. The exception is with postinfarction pericarditis , in which a completed transmural infarct results in inflammation of the subepicardial myocardium and STE in the distribution of the infarct, and which results in increased STE and large upright T-waves. So it is not necessarily subacute.
