| Abstract: | Currently,electrocardiogram is often regarded as the evidence of analyzing heart sounds in the clinic.In terms of the same electrocardiogram,different doctors will be able to get different diagnosis results.In this paper,the sign of heart sounds is directly measured by using the technique of acoustic emission.The virtual instrument technique is applied to the analysis of heard sounds,and the acoustic emission signal analyzer based on LabVIEW for heart sounds is designed.This instrument can display dynamic change characteristic between frequency and extent for heart sounds real time.In addition,programs are worked out by Graphic program language in this essay,and can be operated expediently with friendly interface.It is helpful for the diagnosis of cardiopathy and cardiovascular diseases. |
