Nonstress test; Cardiotocography; WebJan 19, 2024 · The result is reactive if there are two accelerations of fetal heart rate lasting for 15 seconds that occurs after movement. The result is non reactive if there are no fetal accelerations after a fetal movement, or there is no fetal movement. If the nonstress test is nonreactive, a contraction stress test or biophysical profile will be scheduled.

WebOf the final NSTs before delivery, 105 (21.5%) were nonreactive, 151 (30.9%) were reactive by 10-beat criteria, 232 (47.5%) were reactive by 15-beat criteria, and 274 (56.1%) had decelerations. Unadjusted data consistently associated degree of reactivity with outcome and also associated gestational age with degree of reactivity. WebIn conclusion the presence of repeated sporadic decelerations during a reactive NST suggests that the cause of cord compromise is persistent and recurrent cord compression is possible. Therefore, in these cases an increased fetal risk could be expected. MeSH terms Adult Female Fetal Heart / physiology* Fetal Monitoring* Heart Rate / physiology*
