Heart sign obtaining method and device

Abstract

The invention relates to the technical field of computer application, specifically, relates to a heart sign obtaining method and a heart sign obtaining device. The heart sign obtaining method comprises the steps of: obtaining photoplethysmography (PPG) data; performing low-pass filtering processing with cut-off frequency less than or equal to 4 HZ on the PPG value and removing high-frequency noise; performing discrete wavelet filtering processing on the PPG value subjected to high-frequency noise removal and correcting baseline drift; obtaining the wave crest and wave trough positions of PPG waveform according to the PPG data subjected to baseline drift correction, and obtaining the time interval value between the wave crests according to the wave crest and wave trough positions and the sampling rate of the PPG data; obtaining RR interval data according to the time interval value between the wave crests, and calculating the heart sign according to the RR interval data. By adoption of the method and the device, a user can comprehensively obtain the heart sign value.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a method and device for acquiring cardiac signs. Background technique [0002] At present, in addition to the proprietary detection of hospitals and physical examination centers, the current measurement of cardiac signs by users generally focuses on the measurement of heart rate, and the accuracy is low, and other cardiac signs cannot be obtained through heart rate, such as heart rate variability, Cardiac coherence index, cardiac output, degree of distraction, and cardiac mass index, etc. [0003] Therefore, a method that can allow users to obtain more comprehensive cardiac signs at any time has become an urgent problem to be solved. Contents of the invention [0004] In view of this, the purpose of the embodiments of the present invention is to provide a method and device for acquiring cardiac signs, which can allow users to obtain more comprehensive car...
