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. 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.

She was defibrillated and resuscitated. J Electrocardiol [Internet] 2022;Available from: [link] Cardiology opinion: Takotsubo Cardiomyopathy (EF 30-35%) V Fib Cardiac arrest Prolonged QTC NSTEMI (Smith comment: is it NSTEMI or is it Takotsubo? -- these are entirely different) Moderate single-vessel CAD.

A formal echocardiogram was completed the next day and again showed a normal ejection fraction without any focal wall motion abnormalities to suggest CAD. She has not had a heart catheterization or after this event so the presence or absence of CAD is still unknown. The Troponin I was cycled over time and was 0.353 followed by 0.296.

12 minutes later, the patient went back into VFib arrest and underwent another 15 minutes of resuscitation followed by successful defibrillation and sustained ROSC. In total, he received approximately 40 minutes of CPR and 7 defibrillation attempts. EMS found the patient in VFib and performed ACLS for 26 minutes then obtained ROSC.
