Ambulatory Blood Pressure Monitoring for Clinical Applications and Basic Science

Monitoring for spans longer then 24 hours, prefably for 7 days at the outset, has been advocated to obtain more reliable estimates of the circadian characteristics of blood pressure and heart rate. Herein, using data from a chronotherapy tria, we adress the desirability of complementing the global analysis of the entire record by the computation of daily sphygmochrons to gain a better assessment of the day-to-day variability in the circadian patterns of these variables.
