1. An implantable cardiac stimulation device for applying pacing stimulation pulses to a heart and sensing evoked responses to the pacing stimulation pulses, the device comprising:

  • at least one lead adapted for placement in a chamber of a heart, the at least one lead comprising a plurality of electrodes that define a plurality of pacing configurations and a plurality of sensing configurations for the chamber;

    a pulse generator that applies the stimulation pacing pulses to the heart in accordance with a selected one of the pacing configurations;

    a sensor control that maintains lists of potential sensing configurations for each of the pacing configurations, wherein the sensor control is operative to test each sensing configuration in the list for the selected pacing configuration, and to automatically select an evoked response sensing electrode configuration based on the results of the test; and

    a sensor that senses the evoked responses with the automatically selected evoked response sensing electrode configuration.
