The Heart Sounds in Normal and Pathological Conditions

A Hybrid Model of Heart Anomalies Detection by Processing Heart Sounds

​Introduction: Different factors are effective in detecting heart abnormalities. The greater the number of these factors, the greater the uncertainty in the detection of heart abnormalities. In the uncertainty condition in response of prediction model, the fuzzy systems are one of the most effective methods for generating an acceptable response. Method: In this applied study, 3240 records rela...

Computerized heart sounds analysis

This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short-time Fourier transform (STFT), the Wigner distribution (WD) and the wavelet transform (WT) in analysing the phonocardiogram signal (PCG). It is shown that these transforms provide enough features of the PCG signals that will help clinics to obtain qualitative and quantitative measurements of the time-f...

Heart Sounds and Murmurs

In this little pocket-book of 60 Pa.^?' a_ student will find a good deal of usefu tiou put simply and clearly. The text is illustrated with diagrams, showing the characteristics of the murmurs as to time, length and roughness. The book may easily be used for clinical reference and should prove of value to the beginners in acquiring the elements of cardiac ascultation. Many valuable hints are in...

Heart Sounds Biometric System

This paper presents design of system for access control using heart sound biometric signature based on energy percentage in each wavelet coefficients and MFCC feature. A collection of 40 heart sounds records for different persons from internet, for each recording signatures were calculated during two heart cycles after denoising of each recording. A Euclidean distance is used as classification ...
