She had a prior history of "NSTEMI" one month ago, during which she had a coronary angiogram reportedly showing no stenosis in any coronary artery. Electromechanical association: a subtle electrocardiogram artifact. This case was published in Circulation on January 22, 2018 (thanks to Brooks Walsh for finding this!)

Incidence of an acute coronary occlusion. New insights into the use of the 12-lead electrocardiogram for diagnosing acute myocardial infarction in the emergency department. Can J of Cardiol 2018, 34: 132-145 Here are some other cases: LVH, LBBB, RBBB, and RVH may manifest ST depression without any ischemia!

Cardiology felt her chest pain to be, most likely, the result of coronary supply-demand mismatch in the context of HCM endothelial remodeling (i.e. Type II MI), however decided to pursue coronary angiogram out of an abundance of caution. A mid-LAD culprit lesion was identified and stented. Pacing Clin Electrophysiol.

It’s judicious, then, to arrange for coronary angiogram. Coronary occlusion, however, might be present concurrently with subendocardial ischemia on the time-zero ECG, or evolve into such. elevated BP), but rather directly correlated with coronary obstruction and stymied TIMI flow. Does the ECG normalize? 2] Aslanger, E.,
