In the current era of cost-effective delivery of health care, it is particularly timely to carefully reevaluate the clinical utility of selected physical signs. The third heart sound (S3) is one such sign that is the focus of the current review.I conducted a computerized MEDLINE search of articles related to S3 published since 1966.

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 ...

Heart Sounds Interference Cancellation in Lung Sounds
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Several attempts have been made to achieve a quantitative analysis of lung sounds mainly for two purposes: a) an understanding of their genesis, and b) an insight of their changes with pathologies for medical diagnosis. Early studies involved the collection of acoustic information at several positions on the thoracic surface or at the extra-thoracic ...

Gender detection with heart sound
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015In 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.

apical pulse. They heard, but seldom identified, heard sounds. Today, the nurse, as the person most consistently at the patient's bedside can and ought to develop skills in cardiac auscultation so that changes in cardiac sounds, which may indicate a need for therapeutic intervention, can be detected early.

Sounds of the heart in diastole
The American Journal of Cardiology, 1974Abstract 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 ...

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

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.
