Knowledge on heart patients through stethoscopic cardiac murmur identification for E-healthcare

Cardiac murmurs are the sounds produced by the abnormal passage of the blood flow inside the heart due to the diseased valves or tissues. Identifying the type of the murmur can diagnose the cardiac pathology related to that particular murmur. This paper describes a researched digital stethoscope that can be used as a stethoscope as well as a murmur identification device. To capture the heart beat, a chest piece of a traditional stethoscope is used with a condenser microphone attachment. Then the signal is a

Auscultation based stethoscopic diagnostic device for cardiac murmur identification

In a healthy heart, there is no any abnormal blood flow takes place inside, in addition to the usual blood circulating pattern. However when the valves or tissues inside the heart are in diseased conditions, this usual blood flow pattern gets changed. As a result, abnormal sounds are produced with the normal heart beat sound. These abnormal sounds are known as cardiac murmurs. By identifying the murmur type doctors can diagnose the cardiac pathology related to that particular murmur type. This paper describ
