Abstract: A method of operating an implantable blood pump and a pacing device, the method includes determining an end diastolic volume (EDV) and ejection fraction of one from the group consisting of the right ventricle and the left ventricle at a predetermined pump set speed. An average flow rate based on the predetermined pump set speed is determined. A target heart rate based at least in part on the determined EDV, ejection fraction, and average flow rate is determined. A lower rate for the pacing device is determined, the pacing device being in electrical communication with a chamber of the heart. The chamber of the heart is paced when a measured heart rate drops below the lower rate.

Abstract: A method and device apparatus to deliver a pacing therapy capable of remodeling a patient's heart over a period of time that includes delivering remodeling pacing during a first interval, the first interval comprising a first rate and a first duration, determining whether to adjust one or both of the first rate and the first duration during delivery of remodeling pacing during a next interval subsequent to the first interval, and delivering remodeling pacing during the next interval in response to the determining, wherein the next interval comprises one of the first rate and the first duration of the first interval and the adjusted one or both of the first rate and the first duration.
