Fetal ECG signal processing method and fetal ECG signal processing device

摘要

Provided are a fetal electrocardiographic signal processing method and a fetal electrocardiographic signal processing device with which it is possible to reliably and appropriately select a signal including a fetal electrocardiographic component from a plurality of signals separated by independent component analysis with reference. This fetal electrocardiographic signal processing method comprises: a fetal feature display signal extraction step for separating a separation signal for each of multiple channels by independent component analysis with reference from biological signals of the multiple channels acquired from the body of a pregnant mother and removing noise from the separation signal of each channel to extract a fetal feature display signal; and a mother body electrocardiographic signal removal step of removing a fetal feature display signal at a timing at which an electrocardiographic signal of the mother may appear from the fetal feature display signals to obtain fetal feature signals including a large number of fetal electrocardiographic signals.
