1. A method comprising:
- delivering electrical stimulation to a patient'"'"'s heart using a plurality of cardiac electrodes supported inside the patient by one or more at least partially implanted leads and an evaluation unit having an analyzer circuit that is external of the patient and attached to the one or more leads;
receiving user-determined electrode combination selection criteria from a user via the evaluation unit;
evaluating, for each electrode combination of a plurality of electrode combinations of the plurality of cardiac electrodes, one or more first parameters and one or more second parameters produced by the electrical stimulation delivered using the electrode combination, the first parameters supportive of cardiac function consistent with a prescribed therapy and the second parameters not supportive of cardiac function consistent with the prescribed therapy;
selecting one or more electrode combinations of the plurality of cardiac electrodes based, at least in part, on the user-determined electrode combination selection criteria; and
programming an implantable pacing circuit to deliver a cardiac pacing therapy that preferentially uses the selected one or more electrode combinations relative to other electrode combinations of the plurality of cardiac electrodes.

Abstract
Approaches for selecting an electrode combination of multi-electrode pacing devices are described. Electrode combination parameters that support cardiac function consistent with a prescribed therapy are evaluated for each of a plurality of electrode combinations. Electrode combination parameters that do not support cardiac function are evaluated for each of the plurality of electrode combinations. An order is determined for the electrode combinations based on the parameter evaluations. An electrode combination is selected based on the order, and therapy is delivered using the selected electrode combination.

13. A method comprising:
-
delivering electrical stimulation to a patient'"'"'s heart using a plurality of cardiac electrodes; receiving user-determined electrode combination selection criteria from a user, and storing the user-determined electrode combination selection criteria; evaluating, for each electrode combination of a plurality of electrode combinations of the plurality of cardiac electrodes, which electrode combination best satisfies the user-determined electrode combination selection criteria, by delivering electrical stimulation to the patient'"'"'s heart using each electrode combination of the plurality of electrode combinations; selecting the electrode combination that best satisfies the user-determined electrode combination selection criteria; and deliver a cardiac pacing therapy to the patient'"'"'s heart that uses the selected electrode combination. - View Dependent Claims (14, 15, 16, 17)

18. A method comprising:
-
delivering electrical stimulation to a patient'"'"'s heart using a plurality of cardiac electrodes supported inside the patient; receiving user-determined electrode combination selection criteria from a user via a user interface, and storing the user-determined electrode combination selection criteria in a memory; identifying, for each electrode combination of a plurality of electrode combinations of the plurality of cardiac electrodes, one or more electrode combinations that are not supportive of cardiac function consistent with the prescribed therapy by delivering electrical stimulation to the patient'"'"'s heart using each electrode combination, resulting in one or more non-supportive electrode combinations; for each of the plurality of electrode combinations that are not identified as non-supportive electrode combinations, evaluating which of the electrode combination(s) satisfy the user-determined electrode combination selection criteria; selecting an electrode combination that satisfies the user-determined electrode combination selection criteria; and programming an implantable pacing circuit to deliver a cardiac pacing therapy to the patient'"'"'s heart that uses the selected electrode combination. - View Dependent Claims (19, 20)
