Power spectrum and chaos theory analysis, methods recently applied to fetal surveillance, may offer an effective tool for recognising fetal hypoxia and consequential collapse of fetal homeostasis earlier than at present. However, strict continuity and high precision of input data is an indispensable prerequisite. If one overlooks this requirement the results may be misleading. The aim of the present work was to find a method that provides strictly continuous and highly precise beat-to-beat FHR data values. It was found that only the determination of heart beat intervals between successive R peaks, using the digital FECG recording technique developed here, meets the necessary requirements for power spectrum and chaos theory analysis.
功率谱和混沌理论分析是最近应用于胎儿监护的方法，可能为比目前更早识别胎儿缺氧及随之而来的胎儿内环境稳态崩溃提供一种有效工具。然而，输入数据的严格连续性和高精度是必不可少的先决条件。如果忽视这一要求，结果可能会产生误导。本研究的目的是找到一种能提供严格连续且高精度的逐搏胎儿心率（FHR）数据值的方法。结果发现，只有使用此处开发的数字胎儿心电图记录技术来确定连续R波峰之间的心跳间期，才能满足功率谱和混沌理论分析的必要要求。
