  • Configurable intermittent pacing therapy
    Patent number: 8548586
    Abstract: This document discusses, among other things, an apparatus comprising at least one implantable cardiac depolarization sensing circuit, an electrical stimulation circuit, and a pacing mode controller. The implantable cardiac depolarization sensing circuit is configured to obtain a sensed depolarization signal from a ventricle and the electrical stimulation circuit is configured to provide pacing electrical stimulation energy to at least one implantable ventricular electrode. The pacing mode controller delivers pacing therapy according to a first pacing mode that is a normal operating mode, and delivers 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.

  • Deactivation of intermittent pacing therapy
    Patent number: 8483826
    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 pacing is changed from the normal operating mode to a stress augmentation mode. The pacing mode controller suspends the change from the normal operating mode to the stress augmentation mode when a condition to prevent the change is detected.

  • Intermittent pacing therapy delivery statistics
    Patent number: 8140155
    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.
