Assisting physicians in the auscultation of the patients by providing less costly, automatic and accurate signal processing module for the heart event detection and recognition is of great importance. This paper presents a complete heart sound analysis system covering from the segmentation of beat cycles to the final determination of heart conditions. A basic task for the diseases diagnosis fro...

The MIDI interface is originally designed for electronic musical instruments but we consider this music-note based coding concept can be extended for general acoustic signal description. We proposed applying the MIDI technology to coding of biomedical auscultation sound signals such as heart sounds for retrieving medical records and performing telemedicine. Then we have tried to extend our enco...

A2-year-old cachectic cross-breed gelding was admitted toVeterinary Teaching Hospital of University of Tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. Clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. Therespiratory and heart rates were 35/min and 60 bpm, respectively.Agrade III/IV pansystolic murmur...

Heart sounds carry information about the mechanical activity of the cardiovascular system. This information includes the specific physiological state of the subject, and short term variability related to the respiratory cycle. The interpretation of the sounds and extraction of changes in the physiological state, while monitoring short term variability is still an open problem and is the subject...

Cardiovascular diseases are some of the most common today. Congenital abnormalities, caused by impaired heart rhythm, vascular occlusion, post-operation arrhythmias, attacks and irregularities in valves various cardiovascular diseases. Early recognition them is very important for obtaining positive results treatment. For this purpose, it tried to diagnose detect listening sounds coming from hea...

In this exploratory study we propose to analyze, in healthy adult volunteers, the heart electrical (electrocardiogram, ECG) and mechanical (phonocardiogram, PCG) activity during exercise. Heart sounds amplitude, frequency content, and RS2, may be important features in the non-invasive assessment of heart activity, such as for the estimation of cardiac output and blood pressure. Nine healthy vol...
