1. A method comprising:

  • sensing, from a patient, an electrical physiologic signal between a single electrode pair;

    obtaining a cardiac signal component from the physiological signal;

    obtaining a non-cardiac signal component from the physiologic signal;

    comparing the cardiac and non-cardiac signal components to thresholds established for the patient;

    detecting patient activity using at least the non-cardiac signal component; and

    discriminating between voluntary and involuntary activity of the patient based on the comparison and temporal alignment of the cardiac signal component relative to the non-cardiac signal component.
