The Method for Analyzing Photoplethysmogram(PPG) and The Apparatus and The Method for Estimating the Pathological State of a User by Using Thereof

摘要

The present invention relates to an apparatus and method for performing a morphological analysis of a PPG signal waveform and estimating a user's pathology accordingly, and a contraction peak, a starting point of a waveform, and a redundant pulse dent in the PPG signal waveform. PPG analysis unit to detect the; A morphological index calculation unit that calculates a plurality of morphological indices by using the contraction peak, the starting point of the waveform, and the overlapping pulse dent; And a pathology state estimation unit for estimating a pathology state of the user by using the calculated plurality of indices.
