目的评价一种新的系统的准确性，用于测量胎儿心率和ST段变化，使用无创电极在母亲的腹部。使用腹部传感器记录32名足月分娩妇女的胎儿心电图，这些妇女因临床指征而放置了胎儿头皮电极（FSE）。在91.2%的FSE节段和89.9%的腹部电极节段中可获得用于FHR估计的良好质量数据。两种方法计算的FHR数据之间的均方根（RMS）误差为0.36次/分钟。ST与等电点的偏差范围为R波振幅的0至14.2%。两种方法计算的ST段变化之间的RMS误差平均为3.2%。从母体腹部采集的FHR和ST变化非常准确，平均而言，在临床上无法与使用FSE数据计算的FHR和ST变化区分开来。
To evaluate the accuracy of a novel system for measuring fetal heart rate and ST-segment changes using non-invasive electrodes on the maternal abdomen. Fetal ECGs were recorded using abdominal sensors from 32 term laboring women who had a fetal scalp electrode (FSE) placed for a clinical indication. Good quality data for FHR estimation was available in 91.2% of the FSE segments, and 89.9% of the abdominal electrode segments. The root mean square (RMS) error between the FHR data calculated by both methods over all processed segments was 0.36 beats per minute. ST deviation from the isoelectric point ranged from 0 to 14.2% of R-wave amplitude. The RMS error between the ST change calculated by both methods averaged over all processed segments was 3.2%. FHR and ST change acquired from the maternal abdomen is highly accurate and on average is clinically indistinguishable from FHR and ST change calculated using FSE data.
