Why is the patient in shock? He was in profound cardiogenic shock. He was successfully stented. There is an obvious inferior STEMI, but what else? Besides the obvious inferior STEMI, there is across the precordial leads also, especially in V1. This STE is diagnostic of Right Ventricular STEMI (RV MI).

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. This case represents the same physiologic event as OMI in terms of the result on the myocardium, therefore with identical ECG features, however there may not be ACS!

I don’t know whether I can say Yes*, physiologically, the high proximal pressure and low distal pressure help maintain the flow. Mind you, IABP during cardiogenic shock, essentially does this – keep the coroanry diastolic pressure high. Reference 1. Johnson NP, Gould KL, De Bruyne B.
