In order to further understand the use of antepartum fetal heart rate monitoring we measured the distribution, in time, of two, three, or five fetal heart rate accelerations of greater than or equal to 15 bpm for greater than or equal to 15 seconds and of greater than or equal to 10 bpm for greater than or equal to 6 seconds in 12 healthy pregnant women at 38 to 40 weeks' gestation. The length of time necessary to measure 50% or 95% of intervals containing five accelerations would be substantially reduced by changing to a definition of two or three accelerations. However, an observation interval of at least 80 minutes is required to include the longest time interval of two, three, or five accelerations. These data may suggest new strategies for decreasing time and expense of fetal heart rate testing.
为了进一步了解产前胎儿心率监测的应用，我们对12名妊娠38至40周的健康孕妇进行了测量，记录了每分钟胎儿心率加速次数达到或超过15次、持续时间达到或超过15秒，或每分钟达到或超过10次、持续时间达到或超过6秒的两次、三次或五次加速情况随时间的分布。将加速次数的定义改为两次或三次时，测量包含五次加速的间隔时间的50%或95%所需的时间将大幅减少。然而，要涵盖两次、三次或五次加速的最长时间间隔，至少需要80分钟的观察期。这些数据可能为减少胎儿心率检测的时间和费用提供新策略。
