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.

STEMI , ST-segment elevation acute myocardial infarction ). 1 Initial diagnosis of STEMI ECG Management Recommendation Level of evidence A 12-lead ECG should be interpreted immediately (within 10 minutes) at first medical contact. I B ECG monitoring should start immediately and a defibrillator must be ready.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. Perhaps the most common would be fixed CAD and post-cardiac arrest causing hypotension and low flow through the chronic lesion, resulting in true transmural injury but subsides when normal perfusion is returned. CPR was initiated immediately.

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab. She has not had a heart catheterization or after this event so the presence or absence of CAD is still unknown.
