A Review of Computer-Aided Heart Sound Detection Techniques

Abstract EN

Cardiovascular diseases have become one of the most prevalent threats to human health throughout the world.

As a noninvasive assistant diagnostic tool, the heart sound detection techniques play an important role in the prediction of cardiovascular diseases.

In this paper, the latest development of the computer-aided heart sound detection techniques over the last five years has been reviewed.

There are mainly the following aspects: the theories of heart sounds and the relationship between heart sounds and cardiovascular diseases; the key technologies used in the processing and analysis of heart sound signals, including denoising, segmentation, feature extraction and classification; with emphasis, the applications of deep learning algorithm in heart sound processing.

In the end, some areas for future research in computer-aided heart sound detection techniques are explored, hoping to provide reference to the prediction of cardiovascular diseases.
