A system is provided to control operation of an implantable medical device (10) based upon detected EMI (electromagnetic interference). A correlator (20) produces a correlation function indicating the level of an EMI component (14) of an input biomedical signal that includes a biomedical signal component and an EMI component (14), and that is monitored relative to a predetermined threshold to allow the device (10) to operate in a normal manner as long as the intensity or level of the EMI component (14) is such that it does not affect or interfere with device operation. One ore more remedial measures may be selected in the event the level of the EMI component (14) exceeds a predetermined threshold. The system is useful with an electronic device which receives an electronic information signal which may include an EMI component (14). |
