Mechanisms concerned with blood pressure variability throughout the day

Clin Exp Hypertens A. 1985;7(2-3):153-7. doi: 10.3109/10641968509073534.


Blood pressure variability throughout the day has been found to be inversely related to baroreflex sensitivity, as is the response to injected phenylephrine, mental stress and sleep. It is concluded that variability in blood pressure results in some degree from defective buffering of blood pressure by the baroreceptors.
