基于LabVIEW的胎儿心电信号仿真及其时频域分析

Fetal ECG Signal Simulation Based on LabVIEW and Its Time-Frequency Domain Analysis

全球每年有一部分新生儿出生后,患有不同程度的先天性心脏病,因此在胎儿未出生前进行心电信号监测非常重要,它可以了解胎儿的健康状况。目前,胎儿心电信号可通过侵入式和非侵入式获得,由于侵入式提取风险太大,不提倡使用,而非侵入式提取到的胎儿心电信号会受到母体心电信号的强烈干扰。这些原因使得测量真实的胎儿心电数据比较困难,因此有必要进行胎儿心电信号设计仿真,并进行测量分析。

Some newborns around the world have different degrees of congenital heart disease every year. Therefore, it is very important to monitor ECG before the fetus is born. It can understand the health of the fetus. At present, fetal ECG signals can be obtained through invasive and non-invasive methods. Because the risk of invasive extraction is too high, it is not recommended, and non-invasively extracted fetal ECG signals will be strongly interfered by the mother ECG signal. These reasons make it difficult to measure real fetal ECG data, so it is necessary to carry out fetal ECG signal design simulation and conduct measurement analysis.
