Current-based defibrillators may reduce delivered energy with comparable VF shock success; leaves open whether this improves outcomes in randomized trials.
Does a microprocessor controlled current based defibrillator maintain defibrillation success while reducing delivered energy compared to a conventional energy based defibrillator in patients with ventricular fibrillation?
A current-based defibrillator achieves similar defibrillation success rates as conventional energy-based defibrillators but delivers significantly less energy and peak current per shock.
