1. A method comprising:
- evaluating, for each of multiple electrode combinations, one or more first parameters and one or more second parameters produced as a result of an electrical stimulation delivered using each of the multiple electrode combinations, 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 an electrode combination from the multiple electrode combinations based on the evaluated first and second parameters that respectively correspond to each of the multiple electrode combinations;
delivering a patient therapy using the selected electrode combination; and
performing an electrode combination status update, including re-evaluating the one or more first parameters and the one or more second parameters for at least the selected electrode combination.

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.

18. A cardiac rhythm management system comprising:
-
an electrode combination processor circuit configured to; evaluate, for each of multiple electrode combinations available for use by the cardiac rhythm management system, one or more first parameters and one or more second parameters produced as a result of an electrical stimulation delivered using each of the multiple electrode combinations, 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; compare the first and second parameters for each of the evaluated multiple electrode combinations; select for use, for a first therapy duration, a first electrode combination from the multiple electrode combinations based on a result of the compared parameters; and in response to a triggering event, re-evaluate the one or more first parameters and the one or more second parameters for the multiple electrode combinations to determine whether to select a different second electrode combination for use for a second therapy duration; and a therapy circuit configured to deliver a cardiac resynchronization therapy using the selected a selected one of the multiple electrode combinations.
