Abstract
There is disclosed a heart pacer in which the sensed signal is processed in the time domain rather than the frequency domain. A delta modulator operates directly on the sensed electrogram signal, without any intervening filtering, to derive a sequence of bits whose states represent increments or decrements in the sensed signal amplitude. Decisions as to cardiac activity are based on the sequence of bit values thus generated. The particular delta modulator disclosed is highly advantageous in that it allows highly accurate tracking and representation of the sensed signal.
