Right ventricular oxygen saturation (SO2) may be an ideal sensor for determining the rate of an implanted pacemaker. In order to prove this hypothesis, the obtained signals were optimally analyzed; determinations of SO2 at rest and during exercise were made in healthy volunteers and in patients with pacemakers; and an algorithm was developed for varying pacing rate as a function of measured SO2. The results suggest that this method may be applicable to the long-term implantee.
