Document Type and Number:
Japanese Patent JP2016182231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cardiac sound noise removal device, etc. capable of detecting an accurate cardiac sound signal by resampling a cardiac sound signal using a peak interval of an electrocardiographic signal, and removing noise.SOLUTION: A cardiac sound noise removal device includes: a cardiac sound acquisition part 24 for acquiring a cardiac sound signal; an electrocardiographic signal acquisition part 21 for acquiring an electrocardiographic signal; a peak interval acquisition part 22 for acquiring a peak interval of the acquired electrocardiographic signal; a first resampling part 25 for resampling the cardiac sound signal corresponding to the acquired peak interval to a predetermined number of samples for the cardiac sound signal detected at the same time as the acquired electrocardiographic signal; and noise removal means for removing a noise component from the resampled cardiac sound signal.SELECTED DRAWING: Figure 2
