Abstract
A sensing circuit for a cardiac stimulator which can adapt to the use therewith of either bipolar leads or unipolar leads without the need for telemetric programming of a switch internal to the implanted pacemaker. If a unipolar lead is plugged into the terminal receptacle of the pacer at the time of implant, the pacer will sense R-wave activity and other artifacts between a distal tip electrode and the metal body of the pacemaker, but if a bipolar lead is plugged into that same receptacle at the time of implant, the pacer will sense such artifacts between a tip electrode and a ring electrode spaced a predetermined short distance proximally of the tip electrode along the surface of the lead body.
