Abstract
A system is provided that includes one or more electrodes configured to be implanted proximate to a sensing site, and a memory configured to store first and second sets of filter parameters that define first and second noise stop bands. The system also includes an implantable medical device (IMD) that has inputs configured to receive sensed signals, the sensed signals include frequency components associated with physiology activity and frequency components associated with noise. The IMD also includes a band-stop filter communicating with the sensing channel inputs. When executing program instructions, a processor switches the band-stop filter from the first set of filter parameters to the second set of filter parameters to shift from the first noise stop band to the second noise stop band based on the noise in the environment of the patient.
