Abstract
This document discusses, among other things, an apparatus comprising an implantable cardiac depolarization sensing circuit, an electrical stimulation circuit, and a pacing mode controller. The pacing mode controller is configured to deliver pacing therapy according to a first pacing mode that is a normal operating mode, and to deliver pacing therapy according to second and third pacing modes. The second and third pacing modes increase mechanical stress on at least a particular portion of the ventricle as compared to the pacing therapy delivered during the first pacing mode. The pacing mode controller alternates between the second and third pacing modes when switched from the normal operating mode to a stress augmentation mode and stores a statistic related to the stress augmentation mode in a stress augmentation cycle memory area.
