Daftar Isi:
- Various kinds of heart disease have attacked not depend on of age and sex. Because of lifestyle, including fast food, fat and lack of exercise. Types of diseases susceptible to attack is coronary heart disease, the coronary arteries can not provide blood supply to the heart. To make an electronic device for early detection of coronary heart disease, research is needed to determine the characteristics contained of signal. This research has studied the characteristics of coronary heart sound signal in the time and frequency domain, center of gravity that is used for signal classification. The results show that the signal with the specifications ventricular hypertrophy left with abnormal repolisasi obtained the frequency amount 345.2 Hz, time duration of 666.1 ms, and a center of gravity (COG) 413.4 ms, coronary heart disease with specifications lateral infarct and ishemic inferior obtained the frequency amount 354.3 Hz, time duration of 669.1 ms, and a center of gravity (COG) 292.8 ms. While coronary artery infarct with inferior specifications, ishemic and sinus rhythm with ventricular complexes obtained the frequency amount 345.3 Hz, time duration of 656.8 ms, and a center of gravity (COG) 356.7 ms.
