Abstract:
A device for generating a defibrillation signal having plural successive phases with alternating polarities, each of the successive phases consisting of a series of individual defibrillating impulses switching between zero output and a defibrillation output at a frequency higher than a frequency of the successive phases, the device comprising:a low voltage wave generator connected to a primary of a voltage-boosting transformer, said voltage-boosting transformer having a secondary adapted to be connected to a patient; switching means for alternately connecting said primary to ground to provide the defibrillation signal with plural successive phases with alternating polarities, each of the successive phases consisting of a series of individual defibrillating impulses switching between zero output and a defibrillation output at a frequency higher than a frequency of the successive phases.
