Abstract

The invention provides a method for determining biological signal regularity, a device and a method for estimating biological information. The method for determining the regularity of the biological signal comprises the following steps: acquiring a plurality of pulse waveforms of the biological signal; acquiring a plurality of slope waveforms corresponding to the plurality of pulse waveforms; carrying out binarization on the plurality of slope waveforms; acquiring synchronization information of the plurality of pulse waveforms based on binarization of the plurality of pulse waveforms; acquiring a synchronization rate of the reference interval based on the synchronization information; and determining whether the bio-signal is regular or irregular based on the synchronization rate of the reference interval.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2020-0116088 filed with the Korean Intellectual Property Office on September 10, 2020, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Example embodiments of the present disclosure relate to methods of determining regularity of biosignals and techniques for estimating bioinformation by determining regularity of biosignals. Background technique [0003] With an aging population, an increase in medical expenses, and a shortage of medical personnel for specialized medical services, research into an IT-medical fusion technology in which information technology (IT) and medical technology are combined is being actively conducted. In particular, health monitoring systems have extended care from hospitals to patients' homes and offices, allowing patients to monitor their health status in their daily lives. Some examples of biosignals indicating the health...
