Category 1 : Sudden narrowing of a coronary artery due to ACS (plaque rupture with thrombosis and/or downstream showering of platelet-fibrin aggregates. It’s judicious, then, to arrange for coronary angiogram. Supply-demand mismatch (non-occlusive coronary disease, or exacerbation of preexisting flow insufficiency) a.

We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multi-lead ST depression. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ).

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. 3) Anemia, or poisons of hemoglobin such as methemoglobin or CO 4) Fixed coronary stenosis that limits flow.
