1. A method for operating an implanted neural stimulation device having a neural stimulator lead and remote sensing electrodes for sensing cardiac activity from a position remote from a heart, the method comprising:

  • implementing a neural stimulation therapy stored in the implanted neural stimulation device including delivering the neural stimulation therapy through the neural stimulator lead, wherein the neural stimulation therapy does not significantly alter heart rate, and the neural stimulation therapy includes a programmed duty cycle, the programmed duty cycle including a stimulation ON portion followed by a stimulation OFF portion; and

    monitoring cardiac activity, including remotely detecting cardiac activity using the remote sensing electrodes to detect heart rate during implementation of the neural stimulation therapy.
