More past history: hypertension, tobacco use, coronary artery disease with two vessel PCI to the right coronary artery and circumflex artery several years prior. He reports that this chest pain feels different than prior chest pain when he had his STEMI/OMI, but is unable to further describe chest pain.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). With longterm use there may be — bradycardia, AV conduction defects and risk of Torsades de Pointes ( especially in patients also on Digoxin ).

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. It doesn’t meet any conventional STEMI criteria, but there is patently obvious increased area under the curve. No appreciable skin pallor.

Also notice that the arterial line mean arterial pressure is 63 mmHg, but there is no waveform (and SpO2 says "no pulse"), as the flow is continuous on ECMO and the LV function at this point was extremely poor, unable to add a pulse pressure. There is sinus bradycardia with one PVC. She then had a 12-lead: What do you think?

Diffuse ST depression with ST elevation in aVR: Is this pattern specific for global ischemia due to left main coronary artery disease? In my experience, Ive seen U waves not only with low K+/low Mg++ but also in patients with bradycardia, LVH, and sometimes in normal subjects. J Electrocardiol 2013;46:240-8.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI.
