The stethoscope has been used for many years, and has been very effective to diagnose certain cardiologic and pulmonologic sounds. For many years healthcare professionals would listen quietly to patients internal organs so they could diagnose from specific sounds of such internal organs. The objective is to develop a Peripheral Interface Controller based digital Stethoscope to capture the heart...

BACKGROUND A new framework for heart sound analysis is proposed. One of the most difficult processes in heart sound analysis is segmentation, due to interference form murmurs. METHOD Equal number of cardiac cycles were extracted from heart sounds with different heart rates using information from envelopes of autocorrelation functions without the need to label individual fundamental heart soun...

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...

A stethoscope is an instrument used for auscultations to convey heart sounds as well sounds in the other parts of the body. However, traditional stethoscopes are restricted only to audio representation of such sounds and the diagnosis depends on the expertise of the doctor. This project is an attempt to develop an Embedded Stethoscope to capture heart sounds which offers better noise cancellati...

Auscultation of the heart is the most expedient and useful means by which heart disease in animals can be detected. When an experienced clinician finds the heart normal by auscultation, the likelihood of serious heart disease is very low. Definitive diagnosis can be made using a stethoscope (e.g. patent ductus arteriosus). More often a cardiovascular (CV) problem is identified by auscultation, ...
