1. A system to detect impending acute cardiac decompensation of a patient, the system comprising:

  • impedance circuitry to measure a hydration signal of the patient, wherein the hydration signal corresponds to a tissue hydration of the patient;

    an activity sensor to measure an activity signal associated with the patient; and

    a processor system comprising a computer readable memory in communication with the impedance circuitry and the activity sensor, wherein the computer readable memory of the processor system embodies instructions to combine the hydration signal and the activity level of the patient to detect the impending acute cardiac decompensation.
