In 10 ambulant subjects we studied the circadian changes in sympathetic vasomotor control as assessed by the spectral power of the 0.1-Hz low-frequency component of systolic arterial pressure variability measured with a Millar phi 3F tip transducer. The low-frequency component was higher during the daytime, while the subjects were performing light physical activity, and lower during the night, thus paralleling the circadian systolic blood pressure pattern. However, the morning low-frequency rise preceded the blood pressure increase by about 3 h, suggesting that vasometer control and blood pressure control are at least partly related to different mechanisms.
在10名门诊患者中，我们通过使用Millar phi 3F尖端传感器测量的收缩期动脉压变异性的0.1赫兹低频成分的频谱功率，研究了交感神经血管运动控制的昼夜变化。在白天，当受试者进行轻度体力活动时，低频成分较高，而在夜间较低，因此与昼夜收缩压模式平行。然而，早晨低频升高比血压升高提前约3小时，这表明血管张力控制和血压控制至少部分与不同机制有关。
