Abstract
A tissue electrical stimulator and electrical pulse waveform are described. The stimulator or pulse generator may deliver the pules preferably through an endocardial electrode to pace a heart but could be used for other tissue such as nerves or to deliver defibrillation pulses through other means. A preferred circuit is described employing timing of a gate voltage level on an output transistor for the discharge capacitor(s) of the pulse generator. The waveform has a leading edge starting above zero volts and ramps upward for an initial fraction until a saturation voltage is reached and then ramps downward.
