Abstract
A programmable digital atrio-ventricular pacer is provided whereby a single programming circuit is utilized for providing program control signals for control of separate ventricular and atrial pacing circuits. The atrial stimulus circuitry is controlled by a multiple bit control signal to cause derivation of atrial timing signals from the same clock signal as used for deriving ventricular stimulus pulses. A programmable digital multiplier is employed in combination with a counter to set the atrial escape interval independent of the timing of the ventricular stimulus pulses.
