PC based heart sound monitoring system

Heart diseases caused by disorders of the heart and blood vessels, are world’s largest killers. Early detection and monitoring of heart abnormalities is essential for diagnosis and effective treatment of heart diseases. Severalmethodologies are used for screening and diagnosing heart diseases. They are auscultation, electrocardiogram (ECG), echo-cardiogram, ultrasound etc. The effectiveness and applicability of all these diagnostic methods are highly dependent on the equipment cost and size as well as skill of the physician. This paper presents the design and development of a low cost portable wireless/tubeless digital stethoscope which can be used by the physician for monitoring the patient from a distance. The stethoscope system interfaces to a PC and is also capable of analyzing the heart sounds and identifying abnormalities in the heart sound and its classification. Storage of heart sound for later analysis is also possible.This advanced functionality increases the physician’s diagnostic capability, and such a PCG is not still available in most hospitals. Acoustic stethoscope can be changed into a digital stethoscope by inserting an electric capacity microphone into its diaphragm (Wang, Chen and Samjin, 2009).
