She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. Here is a case of ECMO defibrillation with near shark fin that was due to proximal LAD occlusion. The K was normal.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. The morphology of V2-V4 is very specific in my experience for acute right heart strain (which has many potential etiologies, but none more common and important in EM than acute pulmonary embolism). CT angiogram showed extensive saddle pulmonary embolism.

Coronary Artery Disease (CAD) CAD, which involves the narrowing or blockage of coronary arteries due to plaque buildup, can reduce blood flow to the heart. Implantable Cardioverter-Defibrillator (ICD) to help manage dangerous heart rhythms. Heart Transplant may be considered in severe cases where other treatments have failed.

She was defibrillated and resuscitated. To prove there is no plaque rupture, you need to do intravascular ultrasound (IVUS). An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!! link] We know that most type 1 acute MI due to plaque rupture and thrombosis occurs in lesions that are less than 50% (see Libby reference).

Then, part of the thrombus embolized into the LCx causing an inferoposterolateral OMI. (As As an aside, the LCx OMI is a type 2 event, since it is due to supply-demand mismatch from thrombus, and not due to atherosclerotic plaque rupture or erosion). This resulted in anterior/apical infarct and apical thrombus formation.
