This paper focuses on a number of methods for the analysis of the relationship between the arterial baroreflex and different components of blood pressure and heart rate variability. Broad-band spectral analysis techniques have allowed us to obtain experimental evidence that the arterial baroreflex exerts its influence not only on fast but also on slow components of blood pressure and heart rate, i.e., on components with periods longer than 60 sec. Focusing on faster changes in blood pressure and heart rate, both time domain and frequency domain techniques have been developed to track the sensitivity of baroreflex heart rate modulation over time, either in laboratory or in daily life conditions. These approaches have considerably broadened our understanding of the role of baroreflex modulation of the heart and peripheral circulation in a number of pathological and physiological conditions.
本文着重探讨了多种用于分析动脉压力反射与血压及心率变异性不同组成部分之间关系的方法。宽带频谱分析技术使我们能够获得实验证据，表明动脉压力反射不仅对血压和心率的快速成分，而且对其缓慢成分（即周期超过60秒的成分）都有影响。着眼于血压和心率的更快变化，已经开发了时域和频域技术，以在实验室或日常生活条件下跟踪压力反射心率调节随时间的敏感性。这些方法极大地拓宽了我们对压力反射对心脏和外周循环调节在多种病理和生理状况下所起作用的理解。
