Abstract

The invention discloses an intelligent heart sound diagnostic system and method based on in-depth learning and relates to the fields of bio-signal processing, pattern recognition, big data and in-depth learning. The method comprises the following steps: 1) acquiring heart sound audio data by a user through heart sound acquisition equipment or intelligent wearable equipment; 2) transmitting the data to a cloud server through a network, and storing and archiving the heart sound audio data; 3) segmenting the heart sound data on the cloud server by adopting a heart sound segmentation algorithm based on a logistic regression-hidden semi-Markov model, and performing automatic characteristic extraction and classification on the segmented heart sound data by using a one-dimensional convolutional neural network; 4) feeding diagnostic results to the user through a network and storing the results on a cloud so as to be provided for related institutions and designated hospitals as clinical historyreference of the user; and 5) expanding the heart sound data of the user confirmed by a professional doctor serving as training data into a heart sound database of a cloud server, so that the diagnostic capability of the heart sound diagnostic system is continuously improved.

Description

technical field [0001] The invention belongs to the technical fields of biological signal processing, pattern recognition, big data, deep learning, etc., and specifically belongs to a heart sound intelligent diagnosis system and method based on deep learning. Background technique [0002] At present, cardiovascular and cerebrovascular diseases have become the first cause of death among Chinese residents, accounting for more than 40% of the total death toll. Among them, cardiovascular diseases have become a major category of diseases that seriously threaten the health of Chinese residents. According to the "China Cardiovascular Report 2015", the prevalence of cardiovascular diseases is on the rise. At present, it is estimated that there are 290 million cardiovascular disease patients nationwide, including 270 million with hypertension, at least 7 million with stroke, and 2.5 million with myocardial infarction. The number of sudden cardiac deaths in the country is as high as ...
