Abstract:
1. A method for use with an implantable medical system for implant within a patient having a neurostimulation device, the method comprising: sensing far-field cardiac electrical signals using a lead of the neurostimulation device; using the lead to selectively deliver neurostimulation using a set of adjustable control parameters; deriving parameters representative of cardiac rhythm from the far-field cardiac electrical signals sensed using the lead of the neurostimulation device; correlating the parameters representative of cardiac rhythm with neurostimulation control parameters to map neurostimulation control settings to cardiac rhythm parameters; and controlling the delivery of further neurostimulation based on the mapping of neurostimulation control settings to cardiac rhythm parameters; wherein the lead of the neurostimulation device is also equipped to sense neural electrical signals and wherein sensing far-field cardiac electrical signals including distinguishing between the far-field cardiac electrical signals and the neural electrical signals; and wherein the device has a sense amplifier with sufficient bandwidth to sense both far-field cardiac electrical signals and neural electrical signals and wherein distinguishing between cardiac electrical signals and neural electrical signals includes selectively filtering a frequency spectrum sensed by the sense amplifier to separate far-field cardiac electrical signals from neural electrical signals.
