Monitoring fetal heart rate (FHR) variability plays a fundamental role in fetal state assessment. Reliable FHR signal can be obtained from an invasive direct fetal electrocardiogram (FECG), but this is limited to labour. Alternative abdominal (indirect) FECG signals can be recorded during pregnancy and labour. Quality, however, is much lower and the maternal heart and uterine contractions provide sources of interference. Here, we present ten twenty-minute pregnancy signals and 12 five-minute labour signals. Abdominal FECG and reference direct FECG were recorded simultaneously during labour. Reference pregnancy signal data came from an automated detector and were corrected by clinical experts. The resulting dataset exhibits a large variety of interferences and clinically significant FHR patterns. We thus provide the scientific community with access to bioelectrical fetal heart activity signals that may enable the development of new methods for FECG signals analysis, and may ultimately advance the use and accuracy of abdominal electrocardiography methods.
监测胎儿心率（FHR）变异性在胎儿状态评估中起着至关重要的作用。可靠的 FHR 信号可以从有创的直接胎儿心电图（FECG）获得，但这仅限于分娩期间。替代的腹部（间接）FECG 信号可以在怀孕期间和分娩期间记录。然而，信号质量要低得多，并且母体心脏和子宫收缩会产生干扰源。在这里，我们展示了十个二十分钟的妊娠信号和十二个五分钟的分娩信号。分娩期间同时记录了腹部 FECG 和参考直接 FECG。参考妊娠信号数据来自自动检测器，并由临床专家进行了校正。由此产生的数据集表现出多种干扰和具有临床意义的 FHR 模式。因此，我们为科学界提供了获取生物电胎儿心脏活动信号的机会，这可能使 FECG 信号分析的新方法得以发展，并最终促进腹部心电图方法的使用和准确性。
