Patent ID: 8200332

Claim:
A system, comprising: a neural stimulator (NS) device, including: a pulse generator; a controller to communicate with the pulse generator and implement a stimulation protocol to apply neural stimulation at a neural stimulation frequency; and a communications interface to communicate with the controller and to send a neural stimulation status signal; a cardiac rhythm management (CRM) device, including: a controller; a port for connecting a lead with an electrode to sense cardiac activity; and a filter module including an input connected to the port, an output connected to the controller, and a signal path between the input and the output, the filter module including a frequency filter with a transfer response to attenuate a frequency of the neural stimulation; and a switch to selectively place the frequency filter in the signal path, wherein the controller of the CRM device is adapted to receive the neural stimulation status signal, and to selectively actuate the switch to connect the frequency filter in the signal path when the status signal indicates that the neural stimulation device is applying neural stimulation and to remove the frequency filter from the signal path when the status signal indicates that the neural stimulation device is not applying neural stimulation.
