Impact of ambulatory blood pressure monitoring on daily activity.
We evaluated the impact of wearing an ambulatory blood pressure (ABP) monitor on the usual daily activity of 16 healthy men and women. Daily ABP and heart rate (HR) were recorded on 2 days using the DynaPulse 5000 A system. Daily HR and activity were recorded on two further days using a dedicated HR monitoring system. All four sets of measurements were made for 8 h during which time the volunteers kept a simultaneous diary record of their physical activity. There was no detectable difference in physical activity records on any day. Mean daily HR was lower during ABP monitoring than during the dedicated HR monitoring carried out on different occasions (73+/-7 versus 81+/-7 beats min(-1), P<0.001). The lower mean HR observed during ABP monitoring compared with dedicated HR monitoring may reflect subtle differences in the physical behaviour of subjects being monitored, which could not be detected from the diary records.
