FETAL ELECTROCARDIOGRAPHIC SIGNAL PROCESSING METHOD AND FETAL ELECTROCARDIOGRAPHIC SIGNAL PROCESSING DEVICE

摘要

Provided are a fetal electrocardiographic signal processing method and a fetal electrocardiographic signal processing device that can appropriately select a signal reliably including a fetal electrocardiographic component from a plurality of signals separated by independent component analysis with reference.;The fetal electrocardiographic signal processing method according to the invention includes: a fetal feature display signal extraction step of separating separation signals for a plurality of channels from biological signals of the plurality of channels acquired from a pregnant mother, using independent component analysis with reference, and removing noise from the separation signal for each channel to extract a fetal feature display signal; and a maternal electrocardiographic signal removal step of removing the fetal feature display signal at a timing when an electrocardiographic signal of the mother is likely to appear from the fetal feature display signals to obtain fetal feature signals including a large number of fetal electrocardiographic signals.
