Detection of Cardiac Murmur

The project is focused around designing a system that detects the cardiac murmur. So much work has already done in this field and all are efficient but when it comes to cost all of them seems to be costly for a normal people. Thus a system is to be designed that detects the cardiac murmur easily and that is simple to construct and operate. The whole concentration is on accuracy satisfaction and cost of work so that it is easily accessed by anyone anywhere. The designed system takes the cardiac signal and provides it to the sound card and classifies them either normal or cardiac murmur and all the signals are taken in real time. Background In this field many studies are done to design system that can detect the cardiac murmur. Murmurs are simple heart sounds that are produced as a result of blood flow. The sounds because of blood flow is generally normal but sometime due to some reasons like narrowing of valves or leaking of valves or abnormal passage certain problems are caused. A computer aided diagnosis algorithm has been designed and implemented on an ultra cyclone II FPGA to detect cardiac murmurs from recorded heart signals, but system is difficult to implement because of use of FPGA board and also it is difficult to interface with computer system. Thus this tends to design a system that can overcome this problem. Thus the system is designed to achieve the goal of designing a system which can detect cardiac murmur with better accuracy level and ease.
