1. A method of detecting an impending cardiac decompensation of a patient, the method comprising:

  • measuring an electrocardiogram signal of the patient;

    determining an incidence of cardiac arrhythmias from the electrocardiogram signal;

    measuring a bioimpedance of the patient;

    determining from the measured bioimpedance a measure of a tissue hydration of the patient; and

    determining a risk of impending decompensation in response to a combination of the measured tissue hydration and the incidence of cardiac arrhythmias.
