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). American Heart Journal 170(6):1255-1264; December 2015.

Barely any STE, and thus not meeting STEMI criteria. Read our recent editorial: Hyperacute T-waves Can Be a Useful Sign of Occlusion Myocardial Infarction if Appropriately Defined.

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).

This worried the crew of potential acute coronary syndrome and STEMI was activated pre-hospital. As it currently stands, an ST/S ratio >15% should raise awareness for new anterior STEMI. New insights into the use of the 12-lead electrocardiogram for diagnosing acute myocardial infarction in the emergency department.

Background The clinical significance of peak troponin levels following ST-elevation myocardial infarction (STEMI) has not been definitively established. Methods A single-centre retrospective observational study was conducted of all patients with STEMI between January 2015 and December 2017. The mean age was 63.6±12

The HEART and EDACS scores are helpful to risk stratify patients with chest pain, but they hinge on accurate ECG interpretation: a low score doesn’t apply if the ECG shows STEMI(+)OMI, and shouldn’t be used for STEMI(-)OMI or OMI reperfusion either 2.

Figure 1-1 My colleague, a faithful student of ECG interpretation, handed me the tracing and said that it warranted STEMI activation because of apparent terminal QRS distortion (TQRSD) in V2. ASA 324mg was administered while a STEMI activation was simultaneously transmitted to the nearest PCI center. Attached is the first ECG.
