Title:
生体信号解析システム
Document Type and Number:
Japanese Patent JP7294459
Kind Code:
B2
Abstract:
A biosignal analysis system according to the present invention is an integrated biosignal analysis system performing determination of arrhythmia based on electrocardiographic information and includes an input unit configured to receive input of the electrocardiographic information, a data conversion unit configured to perform time-frequency conversion on the electrocardiographic information to generate data for determination, a data restoration unit configured to restore the data for determination using a learned model including an auto-encoder to generate restored data, a difference calculation unit configured to calculate a difference amount between the restored data and the data for determination, and a determination unit configured to determine whether the data for determination is either of normal waveform data and arrhythmic waveform data based on the difference amount.
