Remote sensing in an implantable medical device
First Claim
1. A method for operating an implanted neural stimulation device having a neural stimulator lead and an antenna lead including an electrode, comprising:
- implementing a neural stimulation therapy stored in the implanted neural stimulation device including delivering the neural stimulation therapy through the neural stimulator lead and not through the antenna lead, wherein the neural stimulation therapy includes a programmed duty cycle, and the programmed duty cycle includes a stimulation ON portion followed by a stimulation OFF portion;
remotely detecting cardiac activity using the antenna lead with the electrode to detect heart rate information during at least one of the stimulation ON portion or during the stimulation OFF portion;
controlling the neural stimulation therapy using the detected heart rate information; and
using an accelerometer to detect cough or using an accelerometer to monitor laryngeal vibration.

Abstract
An embodiment uses an accelerometer to sense heart sounds, and determines heart rate information using the sensed heart sounds. An embodiment uses an accelerometer to sense respiratory activity. An embodiment delivers a programmed neural stimulation therapy with a programmed duty cycle, where the programmed duty cycle includes a stimulation ON portion followed by a stimulation OFF portion. An electrode electrically connected to the implanted neural stimulation device is used to remotely detect cardiac activity. The remotely detected cardiac activity is used to detect heart rate information during the stimulation ON portion and to detect heart rate information during the stimulation OFF portion. The detected heart rate information and/or the detected respiration information are used to control a neural stimulation therapy performed by the neural stimulator device and/or are used to provide diagnostic information for the patient'"'"'s condition.
