Seven hundred and twenty-two nonstress tests (NSTs) that were performed on a total of 471 patients were reviewed. The results of the study suggest that the NST is a simple, reliable test as a primary screening procedure in antepartum fetal heart rate (FHR) monitoring. The active and reactive tests were indeed reliable indicators of fetal well-being while the nonreactive test required an additional discriminatory evaluation. A tentative classification is suggested for those cases with FHR decelerations associated with fetal activity and uterine contractions.
回顾了对总共471名患者进行的722次无应激试验（NST）。研究结果表明，NST作为产前胎儿心率（FHR）监测的主要筛查程序，是一种简单、可靠的测试。有反应和活跃的试验确实是胎儿健康的可靠指标，而非反应性试验则需要额外的鉴别评估。对于那些与胎儿活动和子宫收缩相关的FHR减速病例，建议进行初步分类。
