Abstract

The invention provides a heart sound signal classification method and device, equipment and a storage medium. The classification method comprises: when the processor receives to-be-classified heart sound signals sent by a user side, storing the to-be-classified heart sound signals in the cache module, and determining a preset signal classification model corresponding to the to-be-classified heartsound signals in the storage module; the processor acquiring signal characteristics of abnormal standard signals and signal characteristics of normal standard signals in the signal classification model, and acquiring signal characteristics of the heart sound signals to be classified; and the processor comparing the heart sound signals to be classified with the signal characteristics of the abnormal standard signals and the normal standard signals to determine the types of the heart sound signals. According to the method, the heart sound signal classification model is constructed, and the heartsound signals to be classified are determined based on the signal characteristics corresponding to the abnormal standard signals and the normal standard signals, so that the abnormal heart sound signal identification efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a heart sound signal classification method, device, equipment and computer-readable storage medium. Background technique [0002] Heart sound is the result of the interaction between heart blood flow and cardiovascular system, and is a kind of mechanical vibration. The vibration frequency range of normal heart sounds is usually between 20Hz and 200Hz, and the frequency of heart murmurs generally does not exceed 800Hz, which are within the hearing range of the human ear. In view of the mechanism of heart sound generation, heart sound carries a lot of information about the health status of the cardiovascular system, and is an important source of information for diagnosing heart disease and evaluating heart function. At present, the methods for identifying heart murmurs in patients are all judged by doctors auscultating the patient's heart, and the accuracy of judgm...
