Abstract

Electrical stimulation may be delivered to a patient'"'"'s heart using a plurality of cardiac electrodes. Each electrode combination may be evaluated based on one or more first parameters and one or more second parameters. In many cases, the one or more first parameters are supportive of cardiac function consistent with a prescribed therapy and the one or more second parameters are not supportive of cardiac function consistent with the prescribed therapy. The electrode combination selected to deliver a cardiac pacing therapy may be more associated with the one or more first parameters supportive of cardiac function consistent with the prescribed therapy and less associated with the one or more second parameters inconsistent with cardiac function.
