Fetal Heart Rate (FHR) analysis is extremely important to assess fetal well-being during pregnancy. It is crucial to identify parameters able to reduce the inter and intra observer variability in reading FHR signals and to quantify fetal health. In this paper, we introduce a new parameter computed on the Phase Rectified Signal Average curve. The Acceleration Phase Rectified Slope (APRS) is defined as the slope of the PRSA curve in its middle point. APRS resulted to be efficient in discriminating healthy and IUGR patients, at each gestational week. We believe that this parameter can be introduced in the clinical practice to quantify fetal well-being in combination with already used time and frequency domain parameters.
