REPRODUCIBILITY OF BLOOD-PRESSURE AND HEA RT-RATE SHORT-TERM VARIABILITY MEASURED BY USING PLETHYSMOGRAPHIC METHOD IN NORMOTENSIVES

Aim of the study: to assess the reproducibility of blood pressure and heart rate variability measurements in time and frequency domain, by u sing a Finapres device in healthy volunteers. Methods: 16 normotensive subjects aged 22 to 51 years underwent within a 5-day interval two no n-invasive blood pressure recordings by a Finapres device over 15 minu tes both in supine and standing positions, at the same time of the day . Statistical analysis : non parametric tests, relative errors, and in traclass correlation coefficient. Results: [GRAPHICS] Conclusion: the data provided by the FINAPRES device, especially the baroreflex sensit ivity measured in standing position, show a good day to day reproducib ility.
