Multi-sensor strategy for heart failure patient management
First Claim
1. A system comprising:
- a plurality of sensors, each sensor configured to provide a sensor signal that includes physiological information;
a processor, communicatively coupled to the sensors, wherein the processor includes;
a physiological change event detection module configured to;
detect a physiological change event from a sensor signal; and
produce an indication of occurrence of one or more physiological change events; and
a heart failure (HF) detection module configured to;
determine whether the detected physiological change events are indicative of a change in HF status using a first rule applied to the physiological change events;
determine whether to rule out a positive first rule HF determination using a second rule applied to at least one of the physiological change events; and
generate an indication of whether the change in HF status occurred according to the first and second rules.

Abstract
An apparatus comprises plurality of sensors and a processor. Each sensor provides a sensor signal that includes physiological information and at least one sensor is implantable. The processor includes a physiological change event detection module that detects a physiological change event from a sensor signal and produces an indication of occurrence of one or more detected physiological change events, and a heart failure (HF) detection module. The HF detection module determines, using a first rule, whether the detected physiological change event is indicative of a change in HF status of a subject, determines whether to override the first rule HF determination using a second rules, and declares whether the change in HF status occurred according to the first and second rules.
