Patent ID: 8644916

Claim:
A system comprising: a first medical device including: a sensor signal processor configured to receive a plurality of electrical sensor signals produced by a plurality of sensors and at least one sensor signal produced by an implantable sensor; a decision circuit configured to apply a detection threshold to a sensor signal to determine whether an event associated with worsening heart failure (HF) occurred in a subject, and to output an indication of whether the event associated with worsening HF occurred to a user or process; and a first communication circuit configured to communicate information with a second separate device; and a second medical device including: a second communication circuit configured to communicate information with the first device; a port configured to receive information from a third device via a communication network, wherein the information indicates a co-morbidity of a subject; a sensor signal selection circuit configured to select a sensor signal to monitor from among the plurality of sensor signals, according to an indication of the co-morbidity; a threshold adjustment circuit configured to adjust a detection threshold of the selected sensor signal according to the indicated co-morbidity, wherein the threshold adjustment circuit includes a weighting circuit configured to change a weighting that a selected sensor signal is accorded in a HF event determination based on the indication of co-morbidity; and wherein the second external medical device is configured to communicate an indication of the selected sensor signal to monitor and to communicate an indication of an adjusted detection threshold the selected sensor signal to the first medical device.
