The most difficult and problematic task for cardiology specialists is the interpretetation of heart sounds. It requires special skill and clinical experience along with detailed and expensive tests. However, while detection of heart disease heart sound is proffered for the first step of diagnosis . Recently, many Computer aided auscultation has emerged as a cost-effective technique to analyze a...

Carotid bruits are systolic sounds associated with turbulent blood flow through atherosclerotic stenosis in the neck. They are audible intermittent high-frequency (above 200 Hz) sounds mixed with background noise and transmitted low-frequency (below 100 Hz) heart sounds that wax and wane periodically. It is a nontrivial task to extract both bruits and heart sounds with high fidelity for further...

The objective of this study was to determine if a training module improves the auscultation skills of medical students at the University of Maryland School of Medicine. Second-year medical students completed pretests on 12 heart sounds followed by a 45-minute training module on clinical auscultation, with retesting immediately after the intervention and during their third-year pediatrics clerks...

BACKGROUND AND OBJECTIVES Several educators have reported poor identification of abnormal cardiac sounds by primary care residents. Practice and review with cardiology patient simulators and prerecorded heart sounds has been shown to increase the accuracy of diagnosis by medical students and residents. METHODS The participants were 15 members of an urban family practice residency. The residen...

Cardiovasculary diseases are affecting a constantly growing number of people. Due to this reason we are continously looking for new ways of investigations. The processing of the heart’s audio signals also belong to this category. Heart sound is an acoustic wave generated by the mechanical movement of the heart and blood. The sounds can be divided into normal heart sounds and heart murmurs. Murm...

a 5-year-old girl was admitted to the hospital with chest pain, fever and dyspnea. physical examination showed normal heart sounds, diminished pulmonary sounds in the left hemithorax and a normal ecg. on chest x-ray the heart was slightly enlarged with moderate left pleural effusion. ct scan revealed pleural effusion and a hypodense mass at the apex of the heart. a cystic mass was detected by e...

BackgroundHeart sounds (HS) are an important cardiac hemodynamic marker. The capability of a miniaturized three-dimensional (3D) accelerometer (AXL) present in implantable electronic devices (CIED) to detect HS clinical setting, especially heart failure (HF) patients (pts), has not been performed yet.ObjectiveThe objective this investigation was assess the feasibility measuring from 3D AXL on p...

Auscultation, the technique of listening to heart sounds with a stethoscope can be used as a primary detection system for diagnosing heart valve disorders. Phonocardiogram, the digital recording of heart sounds is becoming increasingly popular as it is relatively inexpensive. In this paper, a technique to improve the performance of the Least Square Support Vector Machine (LSSVM) is proposed for...
