    摘要: This document discusses, among other things, systems, devices, and methods measure an impedance and, in response, adjust an atrioventricular (AV) delay or other cardiac resynchronization therapy (CRT) parameter that synchronizes left and right ventricular contractions. A first example uses parameterizes a first ventricular volume against a second ventricular volume during a cardiac cycle, using a loop area to create a synchronization fraction (SF). The CRT parameter is adjusted in closed-loop fashion to increase the SF. A second example measures a septal-freewall phase difference (PD), and adjusts a CRT parameter to decrease the PD. A third example measures a peak-to-peak volume or maximum rate of change in ventricular volume, and adjusts a CRT parameter to increase the peak-to-peak volume or maximum rate of change in the ventricular volume.

    摘要: A cardiac rhythm management system for providing a plurality of therapy modalities. For example, the system may include a cardiac resynchronization therapy module for providing cardiac resynchronization therapy and a pacemaker module for providing bradycardia therapy, as well as a selector module coupled to the cardiac resynchronization therapy module and the bradycardia module. The selector module may select an operating mode from among a plurality of operating modes including the cardiac resynchronization therapy module and the pacemaker module. Various manual and automatic methods may be used to select the operating mode. In addition, a reversion management system may be included to assist the cardiac rhythm management system to recover in case of a disruption to the system.

    摘要: A device and method for delivering electrical stimulation to the heart in a manner which provides a protective effect is disclosed. The protective effect is produced by configuring a cardiac pacing device to intermittently switch from a normal operating mode to a stress augmentation mode in which the spatial pattern of depolarization is varied to thereby subject a particular region or regions of the ventricular myocardium to increased mechanical stress.
