Fetal heart rate response to fetal acoustic stimulation (FAST) during the antepartum period after 25 weeks of gestational age was studied in 157 cases of normal pregnancy, 22 cases of fetal distress, 12 cases of SFD, 10 cases of fetal malformation, 9 cases of placental dysfunction, 4 cases of oligohydramnios, 12 cases of toxemia of pregnancy, and 15 cases of SLE. Five different types of response were observed: Type I through type V. 1. FAST was available to evaluate fetal well-being from 27 weeks of gestational age, although a nonstress test (NST) has been used after 31 weeks of gestational age. 2. Type IV was observed frequently in the case of coiling of the umbilical cord. 3. In acute fetal distress abnormality was detected by NST prior to FAST, but in latent fetal distress abnormality was detected by FAST prior to NST. 4. Cases classified as FAST types III and IV, which remained unchanged or deteriorated to III, IV or V were almost all characterized by poor fetal outcome.
对157例正常妊娠、22例胎儿窘迫、12例胎儿生长受限、10例胎儿畸形、9例胎盘功能障碍、4例羊水过少、12例妊娠中毒症和15例系统性红斑狼疮患者，研究了孕25周后产前期间胎儿心率对胎儿声刺激（FAST）的反应。观察到五种不同类型的反应：I型至V型。1. 尽管在孕31周后使用了无应激试验（NST），但从孕27周起FAST即可用于评估胎儿健康状况。2. 在脐带缠绕的情况下，IV型反应较为常见。3. 在急性胎儿窘迫中，NST在FAST之前检测到异常，但在潜在胎儿窘迫中，FAST在NST之前检测到异常。4. 分类为FAST III型和IV型且保持不变或恶化为III型、IV型或V型的病例几乎均以不良胎儿结局为特征。
