STUDY OBJECTIVES To quantitatively assess autonomic cardiovascular control in normal young adults following exposure to repetitive acoustically-induced arousals from sleep. DESIGN Respiration, R-R interval (RRI) and noninvasive measurements of continuous arterial blood pressure were monitored in subjects during the transition from relaxed wakefulness to(More)
A previous study found that the sympathoexcitatory cardiovascular effects of arousal are relatively long lasting. In this study, we examine (1) whether the cumulative effects of arousal can lead to significant changes in autonomic control and (2) how the frequency of arousals affect the magnitude of these effects. Ten healthy subjects were aroused from(More)
