Abstract The second heart sound can provide important diagnostic information. Although the entire auscultatory examination should be performed with equal care, close attention to the second heart sound may be particularly rewarding. The fact that the interval between the two components of the second heart sound, the intensity of the aortic and ...

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.

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 ...

A simple bedside technique of heart sound simulation using hand and stethoscope is described. The technique utilizes tissue vibration and sound conduction with the usual air column of a stethoscope to reproduce auscultatory events accurately without the distortion that often accompanies electrical production of heart sounds.

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 ...

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.

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
