1. A method comprising:
sensing, by sensing circuitry of a medical device and via each electrode of a plurality of electrodes implanted within an epidural space of a patient, a respective electrical signal indicative of a cardiac signal of a heart of the patient;
determining, by processing circuitry and for each electrode of the plurality of electrodes implanted within the epidural space, a respective value for each respective electrical signal; and
determining, by the processing circuitry, and based on the respective values for each respective electrical signal sensed by each electrode of the plurality of electrodes, a spatial relationship between each electrode of the plurality of electrodes implanted within the epidural space and each other electrode of the plurality of electrodes.
