| Description | Blood pressure (BP) and heart rate (HR) vary greatly, from one individual to another and from moment to moment in any longitudinal record. Variability in BP and HR can be accounted for by genetics, epigenetics, and in response to a variety of stimuli. Reference values in health provide guidelines to distinguish between usual and abnormal variability in BP and/or HR, in terms of deviant circadian characteristics and/or excess/deficit relative to time-specified limits of acceptability. This investigation examines the day-to-day variability in circadian rhythm characteristics determined from analyses of 7-day/24-hour records obtained by ambulatory BP monitoring (ABPM) in Brno, Czech Republic. A novelty pressor effect is quantified by comparing circadian parameters in consecutive days of monitoring. Results interpreted in terms of clinical implications indicate the need to monitor BP around the clock for longer than 24 hours, preferably for 7 days at the outset, in keeping with recommendations from the 2008 consensus meeting held in Brno. |
