N2 - 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 ar-terial pressure variability measured with a Millar ø3F tip trans-ducer. The low-frequency component was higher during the day-time, 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-fre-quency rise preceded the blood pressure increase by about 3h, suggesting that vasometer control and blood pressure control are at least partly related to different mechanisms.
