BackgroundDespite the wellknown importance of witnessed arrest and bystander cardiopulmonary resuscitation (CPR) for outofhospital cardiac arrest outcomes, previous studies have shown significant statistical inconsistencies. The outcome measure was prehospital return of spontaneous circulation (ROSC).

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.

Although one may have all kinds of ischemic findings as a result of cardiac arrest (rather than cause of cardiac arrest), this degree of ST elevation and HATW is all but diagnostic of acute proximal LAD occlusion. This prompted cath lab activation. On arrival to the ED, this ECG was recorded: What do you think?

He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. Some episodes of PMVT would terminate spontaneously — but on many occasions, the PMVT degenerated to VFib, requiring defibrillation.
