ABSTRACT:
A system for internally sensing the cardiac electrogram in a patient with a cardiac pacemaker is disclosed comprising an implanted electrode that, in combination with the metallic case of the pacemaker which acts as an indifferent electrode, senses cardiac electrical signals and provides them as an input to the pacer electronics. The sensing electrode is appropriately spaced from the pacing electrode and positioned so that cross coupling is minimized to permit sensing of the cardiac electrogram without undue interference from the pacing stimulus and after potentials, and so that the pickup of both R- and P-waves is optimized. The sensed signals may be used to control atrial, ventricular or multichamber demand pacemakers and/or may be telemetered out of the patient for pickup and analysis by external equipment. A flat plate and a preferred cylindrical ring form of electrode are described.
