Abstract :

Heart sound is a physical property of heart which contains many information about the cardiovascular system and also do have relation with pulses. In Ayurveda theory the diagnosis depends on pulse duration and time difference between successive pulses. In the present work, heart sound is measure and analyzed for abnormalities detection. Heart sound recorded by using Electronic Stethoscope which contains capacitive transducer. The recorded Signal is then filtered firstly by hardware active filter and then by Wavelet transform in LabVIEW software environment. Also an algorithm is developed for finding optimum peaks present in recorded signal which in turn are the RR interval of ECG waveform. It is found that the proposed method of determining RR interval is parallel to existing methods using ECG signals.
