ABSTRACT:
A pacemaker system which includes an oxygen saturation sensor located near the distal end of a transvenous pacing lead generates a cycle-by-cycle variation of oxygen saturation indicative of the mechanical pumping action of the heart. A timer is used to define a detection window after the generation of a pacing pulse. The occurrence of a detected depolarization within the detection window indicates that the pacing pulses capture the heart.
