Method and apparatus to perform electrode combination selection

摘要

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.

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.
