Abstract

The invention discloses an automatic heart sound diagnosis system based on deep learning, and belongs to the field of medical signal processing, and the system comprises: a heart sound signal processing module which is used for preprocessing a heart sound signal and segmenting the preprocessed heart sound signal into a plurality of heart sound signal segments with the same length; and a heart sound detection module which is used for respectively inputting the obtained heart sound signal fragments into a pre-trained heart sound detection model to obtain a heart sound category of each heart sound signal fragment, and synthesizing the heart sound type of each heart sound signal segment to obtain the heart sound type of the to-be-detected heart sound signal. According to the automatic heart sound diagnosis system based on deep learning provided by the invention, the heart sound signals are automatically detected in an end-to-end manner, the multi-level time sequence features extracted by the LSTM and the local features extracted by the CNN are combined, the advantages of the CNN local feature extraction capability and the LSTM long-term dependence capture capability are fully utilized, and the classification precision is greatly improved.

Description

technical field [0001] The invention belongs to the field of medical signal processing, and more specifically relates to a heart sound automatic diagnosis system based on deep learning. Background technique [0002] Heart disease has become the number one killer threatening human health. About 17 million people die from heart disease every year. Early diagnosis of heart disease is crucial to reducing the mortality rate. Heart sound (PCG) is the sound produced by the mechanical movement of the heart and cardiovascular system, which contains early pathological information of cardiovascular diseases, and has been proven to be effective in detecting potential early cardiovascular diseases. At present, clinicians mainly use traditional stethoscopes to identify heart sounds, and the accuracy of diagnosis results greatly depends on the doctor's personal experience. At the same time, there is a serious shortage of doctor resources in many countries. Heart sounds are used as a preli...
