He had a history of CAD with CABG. Here was his initial ED ECG: There is atrial fibrillation with a rapid ventricular response. Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiac arrest, after defibrillation, and after cardioversion. Does this patient have ACS?

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.

He reportedly told his family "I think I'm having a heart attack", then they immediately drove him to the ED, and he was able to ambulate into the triage area before he collapsed and became unresponsive. It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. CPR was initiated immediately.

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.

He had significant history of CAD with CABG x5, and repeat CABG x 2 as well as a subsequent PCI of the graft to the RCA (twice) and of the graft to the Diagonal. Here is his ED ECG: There is obvious infero-posterior STEMI. A late middle-aged man presented with one hour of chest pain. Most recent echo showed EF of 60%.

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.

Soon after the witnessed occlusion, the patient suffered ventricular fibrillation arrest, from which he was immediately resuscitated with 1 defibrillation. The procedure was described as very complex due to severe multivessel CAD, but ultimately PCI was successfully performed to the ostial LCX. This idea is erroneous.
