1. An automatic mode switch implemented in a medical device comprising:
- a plurality of integrated sensors operatively coupled to a medical device, wherein each of said plurality of integrated sensors provides a signal to the medical device usable to influence a cardiac pacing rate of the medical device and wherein said medical device comprises a dual integrated-sensor operating mode and can mode switch between operating;
in a dual sensor mode, in a single sensor mode, in a non-rate-responsive sensor mode based on the signal from all, one, or none of the plurality of integrated sensors;
means for testing said plurality of integrated sensors by comparing for a given period of time the output signals from each said sensor to other of the plurality of integrated sensors to determine if the sensors are providing physiologically consistent signals; and
for each one of said plurality of integrated sensors that does not provide physiologically consistent signals, means for isolating each one of said plurality of integrated sensors and for switching the coupling of the sensors to the medical device so that each one of the plurality of integrated sensors is decoupled from said medical device such that the medical device operates in one of a single sensor mode and a non-rate-responsive sensor mode.

Abstract
An automatic rate response sensor mode switch is implemented in an implantable medical device to monitor and isolate any sensor in an integrated sensor scheme. The isolated sensor is based on identification of problems associated with the sensor. The implantable medical device will switch to operate with the remainder sensor(s). Specifically, an algorithm tests and determines sensor status to initiate and operate the sensor mode switch. The software continuously monitors, isolates or qualifies a sensor to come back on-line automatically.
