Abstract :
A mathematical model of multisite feedback pacing for defibrillation is optimized for electrode spacing and stimulus period. For four electrodes, the defibrillation success rate is highest at 88% when the electrodes are spaced as far apart as possible. For a single electrode, the optimum success rate was 26%.
