Abstract

Human heart sounds are very natural signals, which have been applied in the doctor's auscultation for health monitoring and diagnosis for many years ago. Auscultation techniques can be applied for diagnosing many heart disorders, which is the most reliable and successful tools for early diagnosis. For heart failure or any heart disease which can bring someone to death, heart sound acquisition is the most trustworthy tools. With no software to easily hear and record the patient's heart sound; this might be not helpful for doctors to observe the condition of their patient's heart especially for the patients with chronic cardiovascular decease. This project will be a helpful system to the doctors because the patient's heart sound can be recorded or heard from the personal computer sound system or their laptop speaker. The purpose of this project is to design a system using Visual Basic 6.0 software application which user can hear the similar sound heard at the stethoscope at the speaker, record the sound and can see the waveform of the sound for comparison or analysis. The Graphical User Interface (GUI) for this system have been designed for user friendly operation and making the software easy to use. The heart sound will be captured by electronic stethoscope and will be connected to the sound card in personal computer or laptop by using the phone jack. The sound that has been recorded can be saved for further analysis. This Heart Sound Acquisition System can be a useful tool for the doctors, health practice, educational purpose or and can be used by those who doing any cardiovascular health analysis or experiments.
