Accurate Classification of Heart Sounds for Disease Diagnosis by A Single Time-Varying Spectral Feature: Preliminary Results

2019 Scientific Meeting on Electrical-Electronics & Biomedical Engineering and Computer Science (EBBT), 2019
Early detection of abnormal heart conditions helps reduce sudden cardiac deaths caused by cardiovascular diseases (CVDs). For this purpose, cardiac auscultation is generally preferred as the first step for heart disease diagnosis.

The maverick heart sound

Heart, 2016
Clinical introduction An asymptomatic 29-year-old woman presented for prenatal counselling. She had a history of a heart murmur since childhood and a previous echocardiogram suggesting ‘enlargement of the heart’. Physical exam revealed normal jugular venous pressure and contour. Precordial palpation was unremarkable.

Automatic Identification of S1 and S2 Heart Sounds Using Simultaneous PCG and PPG Recordings

IEEE Sensors Journal, 2018
Accurate and reliable identification of the first (S1) and second (S2) sounds of the phonocardiogram (PCG) is still a challenging task due to the presence of the S3 and S4, murmurs, high-pitched sounds, physiological interference, and other environmental

The second heart sound

American Heart Journal, 1968
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 ...

The Third Heart Sound

Southern Medical Journal, 1999
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, 2006
Several 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 ...

Handy heart sound simulator

The American Journal of Cardiology, 1975
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.

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 ...
