Abstract
An implantable pacemaker having circuit means for indicating, by pulse width modulation of the delivered pacing pulses, the programmable control states which control the selected pacemaker operating perameters. The circuitry includes a parallel to serial shift register adapted to receive the control states from a pacer circuit and to generate a serial multiple bit word when the pacemaker is switched to a magnetic mode. The shift register is clocked by stimulus timing signals, and the multiple bit word drives a one shot generator, the output of which is combined with the timing pulses to produce pulse width modulated pacing pulses.
