Sensitive noninvasive techniques are available for beat-to-beat measurement of heart rate, blood pressure, and stroke volume. These allow for the assessment of the dynamic response capacity of the autonomic nervous system to stimuli that perturb baseline activity. In this review, the accuracy of volume clamp photoplethysmography for the measurement of finger arterial pressure and impedance cardiography for the measurement of cardiac output is critically evaluated. The utility of spectral analysis of blood pressure and heart rate for the routine assessment of autonomic function is discussed. It is suggested that these techniques will afford valuable information concerning central autonomic regulatory mechanisms and their dysfunction.
有一些敏感的非侵入性技术可用于逐搏测量心率、血压和每搏输出量。这些技术能够评估自主神经系统对干扰基线活动的刺激的动态反应能力。在这篇综述中，对用于测量手指动脉压的容积钳光电容积描记法和用于测量心输出量的阻抗心动描记法的准确性进行了严格评估。还讨论了血压和心率频谱分析在自主功能常规评估中的效用。有人认为，这些技术将提供有关中枢自主调节机制及其功能障碍的有价值信息。
