1. An implantable medical device, comprising:

  • a sensor responsive to physiologic conditions of a patient;

    therapy delivery circuitry coupled to the sensor and providing therapy in response to the sensed physiologic conditions;

    a detector coupled to the sensor and detecting electromagnetic interference and providing a signal indicating the present magnitude of the detected electromagnetic interference;

    an alarm perceptible to the patient and coupled to the detector, activated responsive to the signal indicating that the present magnitude of the detected electromagnetic interference exceeds a defined threshold; and

    control circuitry coupled to the alarm and the sensor ceasing activation of the alarm responsive to the signal indicating that the present magnitude of the detected electromagnetic interference is below the defined threshold.
