摘要：

Diurnal blood pressure (BP) fluctuations are superimposed by a 24-h rhythm with usually lower levels during the night and higher levels during the day. In contrast to other rhythmic bioparameters, the diurnal BP rhythm is largely dependent on activity and sleep rather than on clock time. This has been demonstrated by the BP characteristics after shifted sleeping and working phases, during transition from sleep to wakefulness, and by the influence of sleep and activities on the 24-h BP cur-ve during normal daily routines. Whereas the circadian rhythm of BP is predominantly governed by external time triggers, endogenous rhythmicity can only be detected by time microscopic analysis or in conditions where effects of external time triggers are almost excluded.
