There is sinus bradycardia with one PVC. There is "Shark Fin morphology" I saw this and thought for certain that this was going to be an LAD or left main occlusion as etiology of arrest, and etiology of profound ST Elevation in I, II, aVL, and V3-V6, and ST depression in III, V1 and V2. She then had a 12-lead: What do you think?

If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise. I said I think there is a fixed stenosis in the LAD and the tachycardia and stress caused a type 2 STEMI.

Angiography : LMCA — 90-99% osteal stenosis. LCx — 50-69% stenosis of the 1st marginal branch; with 100% distal LCx occlusion. There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). Principal adverse cardiac effects of Quinidine include QRS widening and QTc prolongation.

This patient is actively dying from a left main coronary artery OMI and cardiac arrest from VT/VF or PEA is imminent! Complete LMCA occlusion is associated with clinical shock and/or cardiac arrest. Below is a still image with the red arrow indicating the subtotal LMCA stenosis.
