1. A method comprising:
- configuring an implantable medical device from a first operating mode to a second operating mode that is less susceptible to undesirable operation in a disruptive energy field than the first operating mode;
setting a timing mechanism to track an amount of time that has elapsed since configuring the implantable medical device from the first operating mode to the second operating mode;
monitoring for presence of the disruptive energy field;
automatically configuring the implantable medical device from the second operating mode to the first operating mode when (i) the amount of time that has elapsed since configuring the implantable medical device from the first operating mode to the second operating mode exceeds a threshold amount of time and (ii) the disruptive energy field was detected before the amount of time exceeds the threshold amount of time and the disruptive energy field is not currently detected; and
continuing to operate the implantable medical device in accordance with the second operating mode when condition (i) is met and no disruptive energy field is detected between when the implantable medical device is configured from the first operating mode to the second operating mode and when condition (i) is met.

Abstract
Techniques may automatically disable an exposure mode that was enabled for operation in the presence of a disruptive energy field. For example, an implantable medical device (IMD) automatically disables the exposure operating mode when (i) the amount of time that has elapsed since enabling the IMD exceeds a threshold amount of time and (ii) a disruptive energy field is detected before the amount of time exceeds the threshold amount of time and the disruptive energy field is not currently detected. When either of these conditions is not met, the IMD continues to operate in accordance with the exposure operating mode.
