Analysis of PCG signals using quality assessment and homomorphic filters for localization and classification of heart sounds

Comput. Methods Programs Biomed., 2018
BACKGROUND AND OBJECTIVE Accurate localization of heart beats in phonocardiogram (PCG) signal is very crucial for correct segmentation and classification of heart sounds into S1 and S2.

Gender detection with heart sound

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
In this work, gender detection was carried out using heart sounds of each persons. The proposed method has three stages to make detection gender with heart sound. First, some features are obtained from heart sounds. Second, modelling is made by Gauss Mixture Model (GMM) by using obtained these features and models are trained.

Sounds of the heart in diastole

The American Journal of Cardiology, 1974
Abstract Cardiac diastole usually is acoustically silent even though several hemodynamic events take place in this phase of the cardiac cycle. In some healthy subjects and in many patients with cardiovascular alterations one or more “extra” heart sounds may be heard in diastole, and in them the distinction between normal and abnormal heart sounds ...

The third heart sound

International Journal of Cardiology, 1985
A unitary concept is proposed to explain the genesis of the third heart sound and associated "rapid filling wave" of the apexcardiogram in physiological and pathological states including constrictive pericarditis. This theory not only clarifies the hitherto unexplained phenomenon such as presence of S3 in significant mitral stenosis, but also places in

The second heart sound

American Heart Journal, 1962
Abstract The second heart sound was studied in 80 patients with systolic or diastolic overload of the right ventricle. In patients who had moderate or severe pulmonary stenosis the second sound was wide and fixed during respiration; it was also wide and fixed in patients who had a considerable left-to-right shunt at the atrial or ventricular level ...

Sound Pulses and the Heart

The Journal of the Acoustical Society of America, 1966
A personal experience is reported for the benefit of persons experimenting with audible repetitive sound pulses. Prolonged exposure to pulses having a repetition rate higher than the normal heart-beat rate appears to fix the cardiac rhythm at an abnormally high rate.
