Patent ID: 7130681

Claim:
An implantable medical device, comprising: a plurality of electrodes for detecting electrical events of a patient; a sensor for detecting mechanical events of the patient; a controller receiving signals, indicative of the detected electrical events, from the plurality of electrodes, and receiving signals, indicative of the detected mechanical events, from the sensor; the controller analyzing an amplitude, a rate, and a variability of the amplitude and the rate of the electrical event signals and the mechanical event signals, and comparing the rate of the electrical event signals with the rate of the mechanical event signals; and the controller selecting a therapy and controlling the therapy delivered by the device to the patient in response to the comparison of the rate of the electrical event signals with the rate of the mechanical event signals, and, if the rate of the electrical event signals does not match the rate of the mechanical event signals, in response to the analysis of each of the signals, wherein the controller adjusts one of a sensing sensitivity corresponding to the detecting by the plurality of electrodes, if the rate of the electrical event signals does not match the rate of the mechanical event signals and the electrical event signals are fast and the mechanical event signals are not one of low amplitude and erratic, and a sensing sensitivity corresponding to the detecting by the sensor if the rate of the electrical event signals does not match the rate of the mechanical event signals and the rate of the electrical event signals is not fast and is not one of absent and erratic.
