title: [Reproducibility of the blood pressure variability parameters by plethysmographic method (FINAPRES) in normotensive subject].
abstract: OBJECTIVE
  to assess the reproducibility of blood pressure and heart rate variability measurements in time and frequency domain, by using a Finapres device in healthy volunteers.
  
  
  METHODS
  16 normotensive subjects aged 22 to 51 years underwent within a 5-day interval two non-invasive blood pressure recordings by a Finapres device over 15 minutes both in supine and standing positions, at the same time of the day.
  
  
  METHODS
  non parametric tests, relative errors, and intraclass correlation coefficient.
  
  
  RESULTS
  [table: see text]
  
  
  CONCLUSIONS
  the data provided by the FINAPRES device, especially the baroreflex sensitivity measured in standing position, show a good day to day reproducibility.
