This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. The VSR is what is causing the cardiogenic shock!

A previously healthy 53 yo woman was transferred to a receiving hospital in cardiogenic shock. Well, don't we see diffuse ST Elevation in Myo-pericarditis (with STD in aVR)? Our chief of cardiology, Gautam Shroff, interprets it differently and thinks this is indeed ischemia. This was sent by a reader. and K was normal.

Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. The patient died of cardiogenic shock within 24 hours despite mechanical circulatory support. There are also J-waves.
