Despite otherwise normal vital signs, she was appropriately triaged to the critical care area of the ED. They are rare and hard to find in normal practice in the ED. She denied chest pain and denied feeling any palpitations, even during her triage ECG: What do you think? Or it could simply still be classic VT. RVEF 100 ml/m2.

Diagnosis of MINOCA should be made according to the Fourth Universal Definition of MI, in the absence of obstructive coronary artery disease (CAD) (no lesion ≥50%).

Smith and Meyers answer: First , LM occlusion is uncommon in the ED because most of these die before they can get a 12-lead recorded. Beware crescendo angina in patient with known CAD ST Elevation in aVR Case 7. Total LM occlusion can present with STE or STD in aVR. The pattern seen may, or may not, be unique to left main occlusion.

This was my thought: if this patient presented to the ED with chest pain, then this is an LAD occlusion. See image below: Slow upstroke, fast downstroke. Asymmetric. NOTE: Any 1 or 2 of the above ECG findings in a patient with new CP would suffice to justify the need for prompt cath with PCI.
