    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: A method and system for determining an optimum atrioventricular delay (AVD) interval and/or ventriculo-ventricular delay (VVD) intervals for delivering ventricular resynchronization pacing in an atrial tracking or atrial sequential pacing mode. Evoked response electrograms recorded at different AVD and VVD intervals are used to determine the extent of paced and intrinsic activation.

    摘要: A maximum pacing rate limiter for use in adaptive rate pacing in conjunction with a cardiac rhythm management system for a heart. The maximum pacing rate limiter may function to measure an interval, termed the ERT interval, between a paced ventricular evoked response and a T-wave. The maximum pacing rate limiter may further function to maintain the ERT interval at less than a certain percentage of the total cardiac cycle. In one disclosed embodiment, a maximum pacing rate limiter calculates an ERT rate based on the detected paced ventricular evoked response and the T-wave, and the pacing rate limiter module further communicates the minimum of the ERT rate and an adaptive-rate sensor indicated rate to a pacemaker.
