1. A method comprising:

  • receiving an input associated with a presence of a magnetic resonance imaging (MRI) device that generates an interfering signal;

    adjusting, in response to receiving the input, a sensing configuration of a sensing module of an implantable medical device to reduce a likelihood of clipping of sensed signals that include noise caused by the interfering signal, wherein adjusting the sensing configuration comprises at least one of increasing an amplitude input range of the sensing module and decreasing an amplitude gain of the sensing module; and

    sensing signals using the adjusted sensing configuration while in the presence of the MRI device.
