Refractory ventricular fibrillation, defined as 3 defibrillation shocks without resolution, was studied via RCT looking to compare ECMO with cardiac cath vs. typical resuscitation
After 30 patients (15 each arm), the trial was stopped because such a significant benefit seen in the ECMO arm
6 patients survived and 3 had good neurological outcomes at 6 months with ECMO
This is compared to 1 patient surviving initially and none surviving at 6 months in the typical resuscitation arm
