FETUS ELECTROCARDIOGRAPHIC SIGNAL PROCESSING METHOD AND FETUS ELECTROCARDIOGRAPHIC SIGNAL PROCESSING DEVICE

摘要

To provide a fetus electrocardiographic signal processing method and a fetus electrocardiographic signal processing device capable of properly selecting a signal including surely a fetus electrocardiographic component from a plurality of signals separated by a reference system independent component analysis method.SOLUTION: A fetus electrocardiographic signal processing method of the invention comprises: a fetus feature display signal extraction step for extracting a fetus feature display signal by processing a signal which is separated by a reference system independent component analysis method from a plurality of channels of biological signals acquired from the body of a mother in pregnancy; and a mother body electrocardiographic signal removal step for acquiring a fetus feature signal including many electrocardiographic signals of the fetus by removing a signal at the timing when an electrocardiographic signal of the body of the mother may appear, from the fetus feature display signal extracted by the fetus feature display signal extraction step.SELECTED DRAWING: Figure 1
