ABSTRACT There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of card- iac stimulating pulses. The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed. In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed. Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis. The pulse generator further includes means for signaling the accept- ance of a programming signal, and means to reset the program acceptance cir- cuit if extraneous signals are detected as programming signals. The program signal acceptance circuit performs several different checks on the detected programming signal including a parity check, an access code check and deter- mining if the proper number of signals were transmitted within a given time. The timing circuit of the pulse generator includes a crystal clock oscilla- tor and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker. The pulse width of each pacemaker pulse is de- termined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreas- ing with time.
