ABSTRACT:
An improved cardiac pacemaker system of the kind that includes an oxygen sensor implantable into a patient's blood stream along with one or two electrical conductors for use in sensing heart beat activity and in selectively applying pacing pulses to the heart muscle. In an embodiment having just one implantable conductor, the oxygen sensor is integrated into the conductor, while in an embodiment having two implantable conductors, the oxygen sensor either is integrated into one of the conductors or is connected between the two conductors, in parallel with the heart muscle. In both cases, the oxygen sensor is selectively used without adversely affecting either heart beat sensing or pacing.
