Fetal heart rate parameters vary significantly by gestational age, highlighting the need to use age-specific reference ranges when interpreting non-stress tests.
Park et al. (2001) conducted an observational in Pregnancy (n=6,455). Gestational age vs. Other gestational age groups was evaluated on Fetal heart rate (FHR) parameters including mean baseline FHR, signal loss, and fetal movements (p=<0.0001). Advancing gestational age was significantly associated with decreased mean baseline fetal heart rate, signal loss, and fetal movements (P<0.0001).
