ABSTRACT:
A battery powered implantable cardiac pacer includes a battery consumption monitor circuit which develops within an internal counter a cumulative count of battery consumption in milliampere hours. The consumption count may be read out to an external indicator by a multiplex circuit to provide to the user an indication of battery life remaining. An over-current feature within the monitor circuit provides an alarm signal in the event that battery consumption exceeds a predetermined maximum level.
