Originální abstrakt

Methods of heart sound pre-processing are compared in this study. These methods are wavelet transform and Fourier analysis in different frequency bands. After pre-processing, the first heart sound was detected. Correlation of the first heart sound with respiration was chosen, as a sign of optimal detection. The results are demonstrated in a study of 30 volunteers. Optimal band selection for heart sound filtering is shown to be strongly individual, and is far more important than selecting Fourier analysis or wavelet transform as filtering method. Correlation with respiration proved to be a good sign for first heart sound detection evaluation.
