Method for efficient delivery of dual site pacing
First Claim
1. A method for controlling a multi-site pacing therapy, the method comprising:
- selecting a first electrode positioned at a first pacing site along a first heart chamber;
selecting a second electrode positioned at a second pacing site along the first heart chamber;
delivering pacing pulses to the first heart chamber using a bipole comprising the first electrode and the second electrode;
determining whether anodal and cathodal capture can be achieved during pacing using the bipole; and
selecting a multi-site pacing configuration comprising the bipole for singly pacing the first and second pacing sites in response to anodal and cathodal capture being achieved.

Abstract
An implantable device and associated method for delivering a multi-site pacing therapy includes electrodes for sensing cardiac signals and delivering cardiac pacing pulses. Electrodes positioned at first and second selected pacing sites are used to deliver pacing pulses to a first heart chamber using a bipole comprising the first electrode and the second electrode. A controller is configured to determine if anodal and cathodal capture can be achieved during pacing using the bipole. Responsive to anodal and cathodal capture being achieved, the controller selects a multi-site pacing configuration comprising the bipole for singly pacing the first and second pacing sites.
