Automatic selection of parameters of an exposure mode of an implantable medical device
First Claim
1. An implantable medical device comprising:
- a memory; and
a processor that automatically determines one or more parameters of an exposure operating mode based on information stored in the memory related to sensed physiological events or therapy provided over a predetermined period of time and switches operation of the implantable medical device from parameters of a current operating mode to the one or more automatically determined parameters of the exposure operating mode,wherein the information stored in the memory includes operating modes of a predetermined period of time, and the processor automatically determines one or more parameters of an exposure operating mode by analyzing pacing therapies provided during the predetermined period of time and selecting an operating mode to be used during the exposure mode based on the analysis.

Abstract
An implantable medical device (IMD) automatically determines at least a portion of the parameters and, in some instances all of the parameters, of an exposure operating mode based on stored information regarding sensed physiological events or therapy provided over a predetermined period of time. The IMD may configure itself to operate in accordance with the automatically determined parameters of the exposure operating mode in response to detecting a disruptive energy field. Alternatively, the IMD may provide the automatically determined parameters of the exposure operating mode to a physician as suggested or recommended parameters for the exposure operating mode. In other instances, the automatically determined parameters may be compared to parameters received manually via telemetry and, if differences exist or occur, a physician or patient may be notified and/or the manual parameters may be overridden by the automatically determined parameters.
