Study Summary
The study compares the effectiveness of two fully approved shock waveforms (monophasic and biphasic shock) commonly used to defibrillate (shock) patients with out-of-hospital cardiac arrest due to a highly lethal rhythm problem (ventricular fibrillation). The purpose of the study (hypothesis) is to determine if one waveform results in improved resuscitation, admission alive to hospital, and discharge alive from hospital compared with the other.
Interventions
- DEVICE Defibrillation (biphasic versus monophasic shock)
