Abstract

The invention is suitable for the technical field of signal processing, and provides a heart sound signal classification method and terminal equipment. The method comprises the steps that heart soundsignals are obtained, the heart sound signals are decomposed and reconstructed, and second heart sound signals of the heart sound signals are extracted; the characteristic frequency of the second heart sound signals is extracted, and the power spectrum density of the second heart sound signals is determined according to the characteristic frequency; the second heart sound signals are classified according to the power spectrum density, and normal heart sound signals and abnormal heart sound signals are obtained. In this way, the normal heart sound signals and the abnormal heart sound signals can be distinguished, a doctor can be assisted in conducting decision and diagnosis, simple, definite and true information is provided for the doctor, the due role of intensive care is played, the diagnosis quality and the level of emergency are improved, the effective treatment time is gained for patients suffering from heart diseases, and the rescue and curative rate for the patients suffering from the heart diseases is increased.

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 the proportion of cardiovascular disease deaths to the total number of deaths is the largest. Cardiac detection and analysis is a key to understand the state of the heart and blood vessels. It is an indispensable means. Electrocardiogram examination is the best monitoring method for cardiac chronotropy and variable conductance, but it cannot be used to monitor cardiac inotropy. Heart sound examination has the advantages of non-invasiveness and good repeatability. It has the advantages of electrocardiogram, ultrasound Cardiography has an irreplaceable diagnostic advantage. With the in-depth development of research work on ...
