But the paramedic and the ED physician in this case did not subscribe to this idea. It is far too premature to say that paramedics and physicians should not be bothered to interpret ECGs labelled as "normal" or "otherwise normal" by the computer algorithm. Thus, this is obvious STEMI(+) OMI until proven otherwise.

The symptoms improved somewhat after the paramedic gave her nitroglycerin. In combination with the subtle ST depression in aVL , these changes are diagnostic for, or at least nearly so, for acute occlusion of a coronary artery, probably with some reperfusion, as inferior T-waves are inverted and the T-wave in aVL is reciprocally upright.

You’re me, and you’re in paramedic school, in the thick of the cardiology section. The ultimate goal is to optimize coronary perfusion pressure (CPP)—in other words, the amount of blood flow into the coronary arteries. When the heart is full, it puts pressure on the myocardium, compressing the coronary microvasculature.
