Abstract
Heart diseases caused by the heart and blood vessels disorders are world’s largest killers. Hence early detection and monitoring of heart abnormalities is essential for diagnosis and effective treatment of heart diseases. This project aims to develop a low cost portable digital stethoscope. The primary function of this system is to work exactly like a normal stethoscope, but having an added advantage of not being limited by the length of the tubing with the help of wireless transmission. At the same time many people can listen to the stethoscope output which is normally impossible with an ordinary stethoscope. It also provides data to visually chart results by connecting to an off-instrument display such as a computer monitor so that further processing and diagnosis of abnormal phonocardiogram will be easy. For real time monitoring and for diagnosis LabVIEW application software is being used and finally a classification study is done using MATLAB and naive bayers classifier. This advanced functionality can increase the physician’s diagnostic capability.
