Measurement of area difference ratio of Photoplethysmographic pulse wave in patients with pre-eclampsia

摘要

BackgroundPreeclampsia (PE) is associated with an increase in maternal arterial stiffness, which may be reflected by photoplethysmography (PPG) of the pulse wave. The aim of this study was to investigate area difference ratio (ADR), a novel parameter derived from PPG, in women with and without preeclampsia.
