Heart rate variability and baroreflex sensitivity derived from finger photoplethysmography during dynamic cerebral autoregulation assessments: Association with age, sex and time of day in healthy volunteers.
Purpose Assessing dynamic cerebral autoregulation (dCA) noninvasively includes continuous blood pressure recording with a photoplethysmography device. We investigated in this retrospective study whether, under these standardized laboratory conditions, the Finapress device can provide feasible measures of heart rate var...
