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 method and apparatus for predicting acute response to cardiac resynchronization therapy is disclosed. The method can comprise measuring a first interval during an intrinsic systolic cycle and measuring a second interval during a stimulated systolic cycle. The acute response can be predicted by comparing the percent change in duration between the first interval and the second interval against a pre-determined threshold value. The first and second time intervals can be measured using, for example, a surface ECG or, alternatively, an intracardiac electrogram. In one embodiment, the first interval can be the duration of an intrinsic QRS complex measured during a non-stimulated systolic cycle. Similarly, the second interval can be the duration of a stimulated QRS complex measured during a stimulated systolic cycle.

摘要： A method and apparatus for determining whether a patient with congestive heart failure (CHF) will benefit from pacing therapy through the use of an implantable cardiac rhythm management device. A patient's right ventricular and left ventricular pressures are measured, and the patient's PP_Area is calculated for each normal heartbeat that occurs during the testing period. Depending upon the value of the patient's mean PP_Area, it can be determined whether the patient will or will not respond well acutely to pacing therapy. A mean PP_Area value of greater than or equal to a predetermined threshold, which is about 0.3, indicates that the patient is a responder to pacing therapy, while a value of less than the predetermined threshold of about 0.3 indicates that the patient is a non-responder.
