ABSTRACT:
A pulse generation and tracking system for connection to an object or a subject under treatment therewith, the waveform being a train of repetitive complex pulses each pulse comprising a large amplitude, short duration positive polarity portion and a small amplitude, long duration negative polarity portion, and a zero value portion. The prescribed pulse train for a subject is delivered by a delivery device, which also provides monitoring of the averaged voltage amplitude of the positive portion in terms of either voltage or current value. The impedance of the subject is expected to change over time and cause the individual pulses to vary from predetermined limits. When this occurs, then a subsequent generation of pulses will be changed so that the pulses are again delivered within the predetermined value limits or boundary. Tracking and generation can be operationally crossed, if desired, so that a voltage out of boundary will cause the current of a subsequent pulse to be changed or vice versa.
