Why the study?
Does rectilinear biphasic waveform defibrillation improve ventricular fibrillation termination rates in out-of-hospital cardiac arrest compared to monophasic damped sine waveforms?
Does rectilinear biphasic waveform defibrillation improve ventricular fibrillation termination rates in out-of-hospital cardiac arrest compared to monophasic damped sine waveforms?
Rectilinear biphasic waveform defibrillation achieves higher rates of ventricular fibrillation termination and return of spontaneous circulation at lower energies compared to historical monophasic damped sine waveforms in out-of-hospital cardiac arrest.
Answers are grounded in this paper and cite their sources.
May support initial lower-energy biphasic shocks in OHCA; hypothesis-generating, with randomized trials needed before practice change.
