We compared a non-invasive fetal electrocardiogram (fECG) to Doppler cardiotocogram (CTG) during the 1(st) stage of labor.
This was a prospective observational study of non-invasive fECG using five abdominal electrodes and one Doppler ultrasound probe in 27 patients. Data were analyzed for reliability, clinical and statistical equivalence.
The fECG was similar to the traditional Doppler method. The fECG characterizes a fetal heart rate (FHR) trace in a similar way with regards to acceleration count, decelerations count and coincidence, variability and baseline. The FHR was overall correlated (Pearson's r=0.91).
This non-invasive fECG presents an alternative, reliable and accurate assessment for fetal well-being during the 1(st) stage of labor.
我们比较了分娩第一阶段的非侵入性胎儿心电图（fECG）与多普勒胎心监护图（CTG）。
这是一项使用五个腹部电极和一个多普勒超声探头对 27 名患者进行的非侵入性 fECG 的前瞻性观察研究。对数据进行了可靠性、临床和统计学等效性分析。
fECG 与传统的多普勒方法相似。fECG 以类似的方式对胎心率（FHR）迹线进行特征描述，包括加速度计数、减速计数和一致性、变异性和基线。FHR 总体上相关（Pearson's r=0.91）。
这种非侵入性的 fECG 为分娩第一阶段的胎儿健康提供了一种替代、可靠和准确的评估方法。
