Other defibrillation strategies studied for refractory V-fib

For patients with refractory ventricular fibrillation during out-of-hospital cardiac arrest, use of double sequential external defibrillation (DSED) or vector-change (VC) defibrillation results in better survival to hospital discharge compared with standard defibrillation, according to a study published online Nov. 6 in the New England Journal of Medicine to coincide with the American Heart Association Scientific Sessions 2022, held from Nov. 5 to 7 in Chicago.
