[Reproducibility of the blood pressure variability parameters by plethysmographic method (FINAPRES) in normotensive subject]. / Reproductibilité des paramètres de variabilité tensionnelle obtenus par photopléthysmographie digitale (FINAPRES) chez le sujet normotendu.

AIM OF THE STUDY: 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. STATISTICAL ANALYSIS: non parametric tests, relative errors, and intraclass correlation coefficient. RESULTS: [table: see text] CONCLUSION: the data provided by the FINAPRES device, especially the baroreflex sensitivity measured in standing position, show a good day to day reproducibility.
