Configuring operating parameters of a medical device based on a type of source of a disruptive energy field

A method comprising:

• detecting, with an implantable medical device, a condition indicative of a presence of a magnetic resonance imaging (MRI) scanner;
• configuring the implantable medical device to operate in accordance with operating parameters of a default exposure operating mode stored in the memory in response to detecting the presence of the MRI scanner;
• subsequently, determining, with the implantable medical device, a type of the MRI scanner;
• selecting, with the implantable medical device and based on the determination, a second exposure operating mode that corresponds to operating parameters for use during exposure to a particular type of MRI scanner;
• and
• configuring the implantable medical device to operate in accordance with the operating parameters of the selected exposure operating mode.

An implantable medical device comprising:

• means for storing a plurality of exposure operating modes, wherein each of the plurality of exposure operating modes corresponds to pacing parameters for use during exposure to a particular type of MRI scanner;
• means for detecting a condition indicative of a presence of a magnetic resonance imaging (MRI) scanner;
• means for determining a type of MRI scanner in response to detecting the condition;
• means for selecting one of the plurality of exposure operating modes based on the determination of the type of MRI scanner;
• and
• means for configuring the implantable medical device to operate in accordance with the operating parameters of the selected exposure operating mode.
