Differentiating decompensation detection based on co-morbidities in heart failure

摘要

This document discusses, among other things, a system comprising 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 memory that includes information indicating a co-morbidity of a subject, a sensor signal selection circuit that selects a sensor signal to monitor from among the plurality of sensor signals, according to an indicated co-morbidity, a threshold adjustment circuit that adjusts a detection threshold of the selected sensor signal according to the indicated co-morbidity, and a decision circuit that applies the adjusted detection threshold to the selected sensor signal to determine whether an event associated with worsening heart failure (HF) occurred in the subject and outputs an indication of whether the event associated with worsening HF occurred to a user or process.

1. An apparatus comprising:
a sensor signal processor configured to receive a plurality of sensor signals, wherein a sensor signal includes physiologic information of a subject; a memory, including information indicating a co-morbidity of the subject; a sensor signal selection circuit, in electrical communication with the sensor signal processor, configured to select one or more sensor signals to monitor from among the plurality of sensor signals according to an indicated co-morbidity in the memory; and a decision circuit configured to determine heart failure (HF) status associated with worsening heart failure (HF) of the subject using the selected combination of sensor signals and generate an indication of the HF status.
