Abstract
An apparatus capable of being implanted in a patient'"'"'s body, including a posture sensor, a heart rate sensor, and a processor coupled to the posture sensor and the heart rate sensor. The processor is configured to measure the patient'"'"'s heart rate via the cardiac signal sensor, detect a change in a posture of the patient'"'"'s body via the posture sensor, and determine an autonomic tone of the patient'"'"'s body based on the patient'"'"'s heart rate measured during a time period corresponding to the change in posture.
