Abstract
Disclosed herein is a pacer signal reject circuit wherein an entire ECG waveform signal is applied to one input of an operational amplifier, while only the initial portion of the pacer signal including the main pulse and a portion of the tail, is applied to the second input of such operational amplifier, to cause cancellation of that initial portion from the ECG signal. Also, a synthesized version of the remainder of such pacer tail is generated and applied to the second input. Thus, by isolating the ECG signal from the second input except for a timed period of the pacer signal, and by applying the synthesized tail signal to such second input, the entire pacer signal may be cancelled.
