A Study on Heart Rate Extraction using Auto-correlation Function for 0-200Hz Sounds

摘要：

A heart rate extraction has been examined from heart sounds using computer signal processings.At first,the heart sounds have been translated to time-depending spectrum using short-time Fourier transform (STFT).Next,a frequency range of 0--200 Hz has chosen to calculate an autocorrelation function,in which first sounds and second sounds of a heart are clearly included.As a result,heart rates have been successfully extraced for normal,normal (young age),dilated cardiomyopathy,congestive heart failure,mitral valve prolapse and lung hypertension cases,but not for hypertension and cardiac arrhythmia ones.
