ABSTRACT:
An implantable cardiac stimulation device which determines stimulation based upon the patient's body position and activity level while eliminating special implantation or calibration procedures. To eliminate such special implantation and calibration procedures, the stimulation device correlates the patient's body position using a multi-axis DC accelerometer or other sensor during times of high activity and determines a patient's standing position value. During other times, the stimulation device compares the signals from the accelerometer to the standing position value to determine the patient's current body position. Based upon the current body position and the activity level, the stimulation device determines the necessary stimulation to deliver to the patient.
