Abstract
Impedance-normalized delivered energy is used as a control parameter in a defibrillation methodolgy and can be selected to yield the highest probability of successful defibrillation while minimizing the risk of damage to the myocardium and nerve system. This control parameter is essentially independent of patient transthoracic impedance and of discharge pulse waveform and duration, thereby making it advantageous as a standard on which a universal defibrillation protocol may be based.
