<P>PROBLEM TO BE SOLVED: To provide an electrocardiogram signal processing method to extract a fetal electrocardiogram signal contained in bioelectric potential signal detected by an electrode attached to the mother's body. <P>SOLUTION: This method is an electrocardiogram signal processing method for extracting an electrocardiogram signal of fetus 1b from the bioelectric potential signal including the electrocardiogram signals of the mother's body 1 and the fetus 1b inputted from the electrode E installed on the pregnant mother's body 1, and includes a reference signal generating step 4 for generating a reference signal to separate and extract the fetal electrocardiogram signal of appointed induction type based on a cardiac cycle signal inputted by detecting element S for detecting the cardiac cycle of the fetus 1b, and an fetal electrocardiogram signal extracting step 5 for separating and extracting the fetal electrocardiogram signal of the appointed induction type by reference frame independent component analyses from the bioelectric potential signal inputted from the electrode E, based on the reference signal generated with the reference signal generating step 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
