ABSTRACT:
A heart pacemaker has circuitry for forming an electrical signal corresponding to the electrode impedance of the pacemaker. The signal is formed by monitoring the stimulation current and the stimulation voltage and dividing those values by each other in a divider. This impedance signal is a measure of the respiration rate of the pacemaker user, and is employed for controlling the pulse rate of the pulse generator of the heart pacemaker in accordance therewith.
