利用自相关数字信号处理技术，分析了３８组临床采样值的分布特征，结合临床经验，作者设计了一种计算心率的经验识别方法，并在此基础上建立运行在ＰＣ计算机的胎儿心率计算机检测处理系统。经４０例临床试验，可满足临床实时监护要求。
Using the autocorrelation digital signal processing technique, the distribution characteristics of 38 groups of clinical samples were analyzed. Based on clinical experience, the author designed a method of empirical recognition of heart rate, and based on this, established a fetal heart rate computer running on a PC computer Processing system. After 40 cases of clinical trials to meet the clinical real-time monitoring requirements.
