Study the signal behavior of phenotypic cardiograph by using filters to determine the condition of cardiac auscultation

چکیده مقاله

1. The blood in the heart and in conclusion the heart sounds change. By knowing the rate of heart beat parameters alone can recognize type of heart disease. For this reason, in this study, the behavior of the heartbeat signal to determine the previous conditions suggested by auscultation based filter. Four heart diseases, of valvular diseases have been considered in the study which includes: Aortic valve regurgitation, aortic valve stenosis, mitral stenosis and pulmonary valve stenosis. Simulation had done in MATLAB software environment and the results of the research in a variety of curves is obtained and presented. The results show the proposed capable and ability method.
