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.
