Abstract
There is disclosed a direct-coupled output stage which is especially advantageous for use in an implantable heart pacer. In order to provide for charge balancing at the electrode/electrolyte interfaces, the electrodes are shorted to each other after a pacing pulse is generated. Not only is the use of a bulky coupling capacitor avoided, but the stored charge dissipates in a much shorter time, thereby minimizing the 'blind' interval in the sensing cycle.
