title: Evaluation of day-by-day variability of home blood pressure using a home blood pressure telemonitoring system.
abstract: BACKGROUND
  There have been no reports indicating how a home blood pressure (HBP) telemonitoring system influences day-by-day HBP variability.
  
  
  METHODS
  We evaluated day-by-day HBP variability using an HBP telemonitoring system, randomizing 60 individuals to either a telemonitoring group or the control group.
  
  
  RESULTS
  There were no significant changes in day-by-day HBP variability between the two groups. However, the SD, root mean sum square differences, and the average real variability values for systolic blood pressure only in the control group in the latter half of the 4-week study were significantly greater than those in the first half (P<0.05).
  
  
  CONCLUSIONS
  A HBP telemonitoring system could be useful in obtaining stable HBP readings over a certain period of time.
