Inventor(s)Ostroff; Alan H. (San Clemente, CA); Mezack; Gary R. (Norco, CA)
AbstractA defibrillator circuit for generating a rectangular waveform across a patient from capacitively stored energy and employing a plurality of capacitors initially chargeable to a common voltage and thereafter sequentially switchable into parallel relation with one another so as to raise the voltage supplied to an H-bridge circuit from a point of decay back to said common voltage.
