What is heart sound diagnosis with manual auscultation?

The duration of S1, S2 and S3 and the relationship between systole and diastole in the heart are marked. Heart sound diagnosis with manual auscultation is a qualitative method entirely based on the experience of the expert through analysis of the tone and intensity of the heart sounds.

What is the framework of heart sound analysis?

The framework of heart sound analysis. After denoising and segmentation, a classifier is trained to produce the prediction and the corresponding interpretation for users (clinicians and patients). The 3 is a normal prediction, and the 7 means the prediction is abnormal. The dashes ‘---’ denote optional procedures.

How computer aided detection techniques can be used for heart sound analysis?

Computer-aided detection techniques for heart sound analysis can obtain the quantized characteristic parameters, which are helpful to find the relationship between the heart sounds and the related diseases. It is conducive to the subsequent traceability of data and the formation of database as well.

Can intelligent auscultation technology be used for heart sound detection?

At present, intelligent auscultation technology has not been widely used in clinical diagnosis, and the main method used for heart sound detection is manual auscultation. Therefore, the research and application of computer-aided techniques for heart sound detection will greatly promote development in the field of cardiovascular disease diagnosis.
