Abstract:
1. A method comprising: using an implantable medical device to determine a change in a posture of a body; determining a change in a physiological parameter in response to the change in posture; and generating a device response as a function of the change in the physiological parameter, wherein the physiological parameter includes one or more of a heart rate, a heart rate variability, a heart sound, a respiration rate, and a blood pressure, and the change in the physiological parameter comprises at least one of: a sensed change in heart rate that is less than a normal subject's change in heart rate; a sensed change in blood pressure that is more than a normal subject's change in blood pressure; a sensed change in heart sound energy that is less than a normal subject's change in heart sound energy; a sensed change in heart rate variability that is less than a normal subject's change in heart rate variability; and a sensed decrease in respiration rate; and further comprising comparing the change in the physiological parameter, the comparison comprising comparing (1) a ratio of the physiological parameter in the first posture to the physiological parameter in the second posture for a subject with a possible health condition, to (2) the ratio of the physiological parameter in the first posture to the physiological parameter in the second posture for a normal subject or population.
