Abstract
An artificial cardiac pacer including a pulse source of relatively high and constant frequency, such as a quartz crystal oscillator, and a frequency divider for converting the source pulses to a lower frequency suitable for application to pacer electrodes for heart stimulation is provided with a pulse rate controller operatively connected to the frequency converter for inhibiting a predetermined number of pulses in each time interval to change the frequency of pulses applied to the pacer electrodes. An external controller operatively coupled to the pulse rate control generates first and second command signals in response to manual selection which are received by the pulse rate control and cause an increase or decrease in the number of pulses inhibited.
