    摘要: An implantable pacemaker is provided with a far-field sensing channel which requires a reduced refractory period during the time when pacing pulses are delivered as compared with sensing channels using intra-cardiac electrodes. The far-field sensing channel may use the conductive housing of the implantable device or can and an indifferent electrode mounted on the device header as the electrodes for its differential inputs. Such a far-field sensing channel is able to sense activity occurring in either the atria or the ventricles for the purposes of arrhythmia detection and/or capture verification.

    摘要: An approach to providing disordered breathing therapy includes detecting disordered breathing and adapting a therapy to mitigate the disordered breathing. The therapy may be adapted to enhance therapy effectiveness, to provide therapy that reduces an impact of the therapy on the patient, or to achieve other therapeutic goals. Cardiac electrical therapy to mitigate the disordered breathing may include various cardiac pacing regimens and/or delivery of non-excitatory electrical stimulation to the heart.

    摘要: Calibration of adaptive-rate pacing by a cardiac rhythm management system using an intrinsic chronotropic response. The cardiac rhythm management system may include an adaptive-rate pacing device. The adaptive-rate pacing device may include an adaptive-rate sensor module for measuring an activity level of the individual. A monitor module may be coupled to the adaptive-rate sensor module, the monitor module monitoring an intrinsic chronotropic response. A calculator module may be coupled to the monitor module, the calculator module calculating a calibrated parameter for the adaptive-rate pacing device based on the intrinsic chronotropic response. An adjuster module may be coupled to the calculator module, wherein the adjuster module adjusts the adaptive-rate pacing device based on the calibrated parameter. The parameters of the adaptive-rate pacing device adjusted by the adjuster module may include a sensor rate target, a maximum sensor rate, and a response factor.

    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 rate-adaptive pacemaker is disclosed in which a sensor-indicated rate is calculated by adding a function of the measured exertion level to a programmed lower rate limit. In the case where the function of the measured exertion level is the difference between a short-term average and a long-term average of the measured exertion level, the lower rate limit is modulated as a function of the long-term average of the measured exertion level and maximum and minimum values of the long-term average of the measured exertion level during a defined extended time period.
