Fetal monitoring using abdominally recorded signals (ADS) allows physicians to detect occurring changes in the well-being state of the fetus from the beginning of pregnancy. Mainly based on the fetal electrocardiogram (fECG), it provides the long-term fetal heart rate (fHR) and assessment of the fetal QRS morphology. But the fECG component in ADS is obscured by the maternal ECG (mECG), thus removal of the mECG from ADS improves fECG analysis. This study demonstrates the performance of the event-synchronous interference canceller (ESC) in mECG removal from ADS data, recorded during pregnancy and labor. Its advantage as a compensation method for extended ADS processing is discussed.
使用腹部记录信号（ADS）进行胎儿监测，可使医生从妊娠初期就检测到胎儿健康状态的变化。主要基于胎儿心电图（fECG），它可提供长期的胎儿心率（fHR）并评估胎儿QRS波形态。但ADS中的fECG成分被母体心电图（mECG）掩盖，因此从ADS中去除mECG可改善fECG分析。本研究展示了事件同步干扰消除器（ESC）在去除妊娠和分娩期间记录的ADS数据中的mECG方面的性能。讨论了其作为扩展ADS处理补偿方法的优势。
