A direct-coupled output stage, which is especially advantageous for use in an implantable heart pacer, includes means (46, 60) for shorting the electrodes (IND, STIM) together after a pacing pulse is generated, in order to provide for charge balancing at the electrode/electrolyte interfaces. 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. <IMAGE> |
