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 a user-determined electrode combination selection criteria from a user via the evaluation unit, wherein the user-determined electrode combination selection criteria indicate one or more boundary conditions comprising one or more of a maximum pulse amplitude at which the implantable pacing circuit is programmed to deliver, a minimum pulse amplitude at which the implantable pacing circuit is programmed to deliver, a maximum pulse width at which the implantable pacing circuit is programmed to deliver, a minimum pulse width-at which the implantable pacing circuit is programmed to deliver, and wherein the user-determined electrode combination selection criteria further indicate which electrode combinations of the plurality of cardiac electrodes will be used to deliver electrical stimulation and be evaluated;

    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;

    displaying an indicator for each of a plurality of electrode combinations of the plurality of cardiac electrodes on a user interface of the evaluation unit;

    accepting a selection of one of the plurality of electrode combinations having an indicator displayed on the user interface of the evaluation unit from a user via the user interface of the evaluation unit; and

    programming an implantable pacing circuit to deliver a cardiac pacing therapy that preferentially uses the user-selected electrode combinations relative to other electrode combinations of the plurality of cardiac electrodes.
