1. A method of detecting a lead-related condition associated with a medical electrical lead having an electrode and a plurality of conductors, wherein each of the plurality of conductors is coupled to the electrode, the method comprising:

  • monitoring signals transmitted through the plurality of conductors;

    evaluating the signals for each of the conductors to detect an electrical property indicative of the lead-related condition;

    employing an arbitration scheme to select one of the conductors for propagation of a signal sensed by the electrode based on the evaluation; and

    coupling the selected conductor to sensing circuitry of an implantable medical device.
