Abstract
The technology used in cardiotocographs limits the basic resolution of the recorded data. The limitations and errors generated by the data collection, signal processing (autocorrelation) and printing the fetal heart rate (FHR) are discussed. Although adequate for displaying baseline variability, present-day cardiotocographs are incapable of displaying beat-to-beat changes in FHR.
摘要
胎心监护仪所使用的技术限制了记录数据的基本分辨率。本文讨论了数据收集、信号处理（自相关）以及打印胎儿心率（FHR）过程中产生的局限性和误差。尽管如今的胎心监护仪足以显示基线变异性，但无法显示FHR的逐搏变化。
