A passive sensing reference electrode 10 is positioned on an implantable pulse generator 12 arranged to supply stimulation pulses to a stimulation electrode and an indifferent or stimulation reference electrode and the sensing reference 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 16a, on a surface of a hermetically sealed metallic pacemaker can 14, or one of the surfaces of the pacemaker can may be insulated from other surface of the pacemaker can where one part of the pacemaker can may serve as the passive sensing reference electrode. |
