Abstract
Passive sensing reference electrode positioned on an implantable pulse generator where the electrode electrically contacts with tissue or body fluid. The electrode configuration reduces stimulation afterpotentials due to electrode polarization and output capacitor recharge by using the passive sensing reference electrode for sensing. The passive sensing reference electrode may be located adjacent the conductor sleeve, on a surface of a hermetically sealed metallic pacemaker can, or one of the surfaces of the pacemaker can may be insulated from another surface of the pacemaker can where one half of the pacemaker can may be the passive sensing reference electrode.
