1. A method for determining a cause of an irregularity in physiologic data collected by an implanted medical device (IMD), the method comprising:

  • monitoring and storing a collected physiologic characteristic of a patient through the physiologic data in memory of the IMD, the physiologic data collected by the IMD;

    detecting an irregularity in the physiologic data, wherein the irregularity is due to a non-motion cause that is unrelated to the physiologic characteristic being monitored;

    monitoring and storing position data of the patient in the memory of the IMD, the position data collected by a position detector in the IMD;

    automatically correlating the physiologic data with the position data; and

    determining that electromagnetic interference is the non-motion cause of the irregularity in the physiologic data when the position data does not include an aberration correlated in time with the irregularity in the physiologic data.
