Abstract
The authors investigated the difference in spectral composition of first (S1) and second (S2) heart sounds before and after mechanical prosthesis implantation. The frequency spectrum was obtained using the forward-backward overdetermined Prony´s method. It is shown that the difference in spectra before and after mechanical valve implantation yields useful information regarding the frequency characteristics of the heart-chest system and the valve itself
