摘要
目的 研究基于母亲腹部胎儿心电（fetal electrocardiogram,f ECG）提取技术的便携式胎儿/母体心率记录仪Monica AN24行连续监护的胎儿心率记录质量（recording quality,RQ）,以验证和评价f ECG技术采集非产时胎儿心率的可行性以及准确率。方法 将98例孕36~41＋6周的孕妇纳入本研究,使用胎儿/母体心率记录仪Monica AN24连续记录15 h胎儿心率数据,记录每小时以及15 h平均记录质量;当RQ≥60%时,定义记录质量良好。结果 16.8%的病例出现单小时RQ低于60%,100%病例在连续15 h监护时间内RQ≥60%。不同时段RQ总体具有统计学差异,P〈0.001,在夜间（4：00 am-5：00am）RQ达到最大值（98.6%±4.2%）。在该时段,不同孕周RQ、高危与无合并症孕妇RQ在组间不存在统计学差异;RQ与孕妇BMI、孕妇腹围、胎儿体重不存在显著相关性。结论 采用f ECG技术可获得良好的RQ,在夜间4：00 am-5：00 am时间段达到最高值,且RQ不受孕周、孕妇BMI及孕妇腹围等因素影响,可作为连续监护高危胎儿心率的有效方法。
Objective To analyze and evaluate the feasibility and accuracy of fetal heart rate of recording quality （RQ） based on long-term transabdominal fetal electrocardiogram （fECG）. Methods According to the inclusion criteria （singleton, 36-41＋6 weeks） , 98 cases were enrolled in this study. Monica AN24 continuously recorded fetal heart rate for 15 hours, obtaining RQ of 15 hours and RQ of each hour. When RQ〉~60%, it was defined qualified. Results There were 16.8% cases of RQ of each hour lower than 60%, 100% cases of RQ of 15 hours were larger than 60%. RQ of 4：00 am-5：00 am was the best （98.6%-＋4. 2% ） , and there was no statistical significance among different gestational age, between high risk and low risk pregnant woman in this period. There was no correlation between RQ and maternal BMI, fetal weight, as well as abdominal circumference. Conclusions Qualified RQ can be obtained from Monica AN24 and RQ is not affected by gestational age, maternal BMI, maternal abdominal circumference, etc. fECG is an effective method of monitoring fetal heart rate of high-risk cases continuously.
