The baroreflex is a closed-loop system with a feedback (blood pressure to sinus rate) and a feedforward arm (heart rate to blood pressure). We have shown previously that the contributions of the two closely intertwined baroreflex components can be separated by system identification techniques. This study is designed to validate this concept by comparing both methods of baroreflex sensitivity testing in a group of normal volunteers.

压力反射是一个闭环系统，具有反馈（血压到 窦性心率）和前馈臂（心率对血压）。 我们 之前已经表明，两者的贡献密切相关， 相互缠绕的压力感受性反射成分可以通过系统分离， 识别技术。 本研究旨在验证这一点 通过比较两种方法的压力反射敏感性测试的概念， 一组正常的志愿者。
