胎心率(FHR)监测是一种在产前评估胎儿健康的有效手段。目前，用于产生这些数据的唯一广泛可用的仪器是基于多普勒超声的，这是一项不适合长期使用的技术。近一个世纪以来，人们已经知道，使用放置在孕妇腹部的电极可以检测到胎儿的光体积描记(FPPG)。本文介绍了一种紧凑型、长期三通道产前24小时经腹数据记录仪的设计、结构和使用方法。该记录器在大约400个短记录时段的初步使用表明，可以从这些数据中提取与基于多普勒超声的仪器相同质量的胎心率记录。平均而言，从怀孕20周左右开始，FHR衍生的成功率约为记录期的65%(尽管这一数字从约28-32周减少，而且当考虑到个别受试者时，成功率表现出很大的差异)。这些结果表明，该技术不仅提供了一种获取通过其他方法难以获得的长期FHR数据的方法，而且还提供了一种比多普勒超声技术更方便患者的替代方法。
Fetal heart rate (FHR) monitoring is a proven means of assessing fetal health during the antenatal period. Currently, the only widely available instrumentation for producing these data is based on Doppler ultrasound, a technology that is unsuitable for long-term use. For nearly a century, it has been known that the fetal Photoplethysmography (FPPG) can be detected using electrodes placed on the maternal abdomen. The paper describes the design, construction and use of a compact, long-term recorder of three channels of 24 h antenatal transabdominal data. Preliminary use of the recorder in around 400 short recording sessions demonstrates that FHR records of equivalent quality to those from Doppler ultrasound- based instruments can be extracted from such data. The success of FHR derivation is, on average, around 65% of the recording period from around 20 weeks gestation (although this figure is reduced from around 28-32 weeks, and the success rates exhibit a wide range when individual subjects are considered). These results demonstrate that the technique offers, not only a means of acquiring long-term FHR data that are problematic to obtain by other means, but also a more patient-friendly alternative to the Doppler ultrasound technique.
