Abstract

The invention is applicable to the technical field of signal processing, and provides a heart sound signal classification method and terminal equipment. The method comprises: acquiring a heart sound signal, decomposing and reconstructing the heart sound signal, extracting a second heart sound signal of the heart sound signal; extracting the characteristic frequency of the second heart sound signal, and determining the power spectral density of the second heart sound signal according to the characteristic frequency; The power spectral density classifies the second heart sound signal to obtain normal heart sound signal and abnormal heart sound signal. After adopting the above scheme, normal heart sound signals can be distinguished from abnormal heart sound signals, which can assist doctors in decision-making and diagnosis, provide simple, clear and real information for doctors, play the role of intensive care, and improve the quality of diagnosis and emergency response. The level has won effective treatment time for heart patients and improved the treatment rate of heart patients.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a heart sound signal classification method and terminal equipment. Background technique [0002] With the improvement of material living standards in modern society, cardiovascular disease is on the rise in our country. Statistics show that cardiovascular disease deaths account for the largest proportion of the total number of deaths. Heart detection and analysis is an important part of understanding the state of the heart and blood vessels. It is an indispensable means. ECG is the best method for monitoring the chronotropy and conductivity of the heart, but it cannot be used to monitor the inotropy of the heart. The heart sound test has the advantages of non-invasiveness and good repeatability. The irreplaceable diagnostic advantage of cardiography, with the in-depth development of research on the mechanism of heart sound and the characteristics of cardioth...
