Method for efficient delivery of dual site pacing
First Claim
1. A method for controlling a multi-site pacing therapy, the method comprising:
- delivering pacing pulses to an electrode positioned at a first pacing site along a heart chamber;
measuring an activation time at each of a plurality of pacing electrode sites along the heart chamber in response to pacing being delivered to the first pacing site; and
identifying a second pacing site from the plurality of electrode sites in response to the activation times measured during pacing at the first pacing site,the second pacing site identified as one of the plurality of pacing electrode sites having a latest activation time during pacing at the first pacing site,the second pacing site identified for delivering the multi-site pacing therapy in the heart chamber wherein capture would occur at the first pacing site and at the identified second pacing site.

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 to a first pacing site along a heart chamber and a therapy delivery module for delivering cardiac pacing pulses to a patient'"'"'s heart via the electrodes. A sensing module measures an activation time at multiple pacing electrode sites along the heart chamber in response to delivering pacing pulses at the first pacing site. A controller is configured to identify a second pacing site from the plurality of pacing electrode sites in response to the activation times measured during pacing at the first site.
