Abstract
A battery test circuit for a heart pacemaker has a stimulation pulse counter and input logic which identify the consumed charge from the operating values of the pacemaker, from the number of stimulation pulses emitted, and from a time-dependent base value. The consumed charge identified in each test is summed in a charge counter. The content of the charge counter is accordingly a measure for the total charge consumed.
