Question 1: What is the rhythm? Beat 1 : Sinus, narrow QRS complex. The assumption is that a premature complex discharged prior to Beat 1, which prolonged its respective refractory period in the same manner as Beat 5. The coronary angiogram revealed no critical stenosis, or acute plaque ulceration.

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. The patient proceeded to cath where all coronaries were described as normal with no evidence of any CAD, spasm, or any other abnormality. So maybe she is better than I am.

We who know ischemic ECGs know that really when T-wave inversion is specific for coronary thrombosis that it indicates reperfusion of the artery, not active occlusion. Learning Point: 1.

We recorded an ECG in which V1-V3 were put in the position of V4R-V6R, and V4-6 were placed in V7-9 to (academically) confirm posterior OMI. 1 mg of Atropine was given and the heart rate increased transiently to 60. Atropine usually works in junctional rhythm with a narrow complex 9. What to do? RVMI explains part of the shock.
