Although the patient reported experiencing mild pressure-like chest pain, there was suspicion among clinicians that this might be indicative of an older change. There is some ST-segment elevation in DII, DIII, aVF, V4-6. Due to the observed ST-segment elevation, the medical team expressed immediate concern.

While this ECG is negative for “posterior STEMI”, the resolution of anterior ST depression (accompanied by the troponin elevation) confirms posterior OMI with spontaneous reperfusion. The second opportunity to make the diagnosis and expedite angiography was missed because the ECG never met STEMI criteria and continued to be labeled ‘normal.’

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.

All bets would be off if instead of no chest pain, this patient had worrisome new-onset symptoms. Nevertheless, it has the look of LVH. Peguero JG et al.
