Title:
BIOLOGICAL SIGNAL ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/113792
Kind Code:
A1
Abstract:
This biological signal analysis system is a series of biological signal analysis systems that determine arrhythmia on the basis of electrocardiographic information, the biological signal analysis system comprising: an input unit that receives input of electrocardiographic information; a data conversion unit that generates determination data by performing time/frequency conversion on the electrocardiographic information; a data restoration unit that generates restored data by restoring the determination data using a learned model constituted of an autoencoder; a difference calculation unit that calculates the difference between the restored data and the determination data; and a determination unit that determines whether the determination data is normal waveform data or arrhythmic waveform data on the basis of the difference.
