To define reference ranges for fetal heart rate (FHR) parameters after vibroacoustic stimulation (VAS) according to gestational age by determining the relationship between FHR and gestational age using a computerized analysis system.
Data were analyzed from 3453 women using 10-minute observational recordings during nonstress testing (NST) and VAS testing. FHR parameters were analyzed according to gestational age.
All FHR parameters were related to gestational age except for mean baseline FHR, which did not vary significantly with gestational age. All other parameters followed trends similar to the NST results, except for decelerations.
FHR parameters after VAS differed significantly according to gestational age. The results suggest that the gestational age of the fetus should be considered when interpreting FHR patterns after VAS.
通过使用计算机分析系统确定胎心率（FHR）与孕周之间的关系，来定义不同孕周的胎儿在接受声振刺激（VAS）后的FHR参数参考范围。
对3453名女性在无应激试验（NST）和声振刺激试验期间进行的10分钟观察记录数据进行分析。根据孕周对FHR参数进行分析。
除平均基线FHR外，所有FHR参数均与孕周相关，平均基线FHR随孕周变化不显著。除减速外，所有其他参数的变化趋势与NST结果相似。
VAS后的FHR参数因孕周不同而有显著差异。结果表明，在解读VAS后的FHR模式时应考虑胎儿的孕周。
