Heart murmurs are the first signs of cardiac valve disorders. Several studies have been conducted in recent years to automatically differentiate normal heart sounds, from heart sounds with murmurs using various types of audio features. Entropy was successfully used as a feature to distinguish different heart sounds. In this paper, new entropy was introduced to analyze heart sounds and the feasi...

a 16-month-old holstein heifer with a history of anorexia and respiratory distress was referred to the veterinary research and teaching hospital of tehran university. heart and lung sounds were inaudible on the left side but greatly increased on the right side. on electrocardiography (ecg), decreased amplitudes of ecg parameters were observed. ultrasonography results revealed a pleural effusion...

in human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating qrs amplitude (electrical alternans). however, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. a 3-year-old male crossbreed dog was presented with a history of car accident. thoracic au...

Digital stethoscopes offer new opportunities for computerized analysis of heart sounds. Segmentation of heart sound recordings into periods related to the first and second heart sound (S1 and S2) is fundamental in the analysis process. However, segmentation of heart sounds recorded with handheld stethoscopes in clinical environments is often complicated by background noise. A duration-dependent...

Heart sounds give us information about the state of the heart. Heart diseases can be detected at an earlier stage by analyzing the heart sounds. In this paper, detailed discussion of various methodologies that have been used earlier to analyze the heart sounds has been carried out. Comparison has been done on the basis of methodology used and the performance achieved.

Coronary heart disease is a leading cause of death around the world. Early and accurate detection this vital to reducing complications preventing failure attacks. This project creates an early-level diagnosis method that analyzes sound audio detect characterize anomalies including murmurs, arrhythmias, extra sounds. The dataset was obtained from Peter Bently’s Classifying Heart Sounds Database....
