Heart rate reactivity is thought to be a good indicator of normal fetal autonomic function.
WebJul 6, 2024 · Decelerations are an abrupt decrease in the baseline fetal heart rate of greater than 15 bpm for greater than 15 seconds. The fetal heart rate is controlled by the autonomic and somatic nervous system. In response to hypoxic stress, the fetus reduces its heart rate to preserve myocardial oxygenation and perfusion. Unlike an adult, a fetus ...

WebThe nonstress test (NST) is a widely applied technique for antepartum fetal assessment despite a high false-positive rate. The evidence regarding the clinical significance of a single sporadic variable deceleration (SSD) in fetal heart rate (FHR) during reactive NST is scarce, and therefore, the optimal management of SSD in a term pregnancy
