Abstract
A system for determining a patient's posture by monitoring heart sounds. The system comprises an implantable medical device that includes a sensor operable to produce an electrical signal representative of heart sounds, a sensor interface circuit coupled to the sensor to produce a heart sound signal, and a controller circuit coupled to the sensor interface circuit. The heart sounds are associated with mechanical activity of a patient's heart and the controller circuit is operable to detect a posture of the patient from a heart sound signal.
Claims20

- sensing heart sounds associated with activity of a patient's heart using an implantable medical device;
- discriminating a posture of the patient from among a plurality of postures from the heart sounds;
- and
- providing an indication of patient posture to a user or process.
