Abstract :
The seismocardiogram (SCG) is a complex, nonstationary signal used for pathological analysis of cardiac vibratory activity. This article reports the results of multiresolution wavelet decomposition of SCGs for a normal male subject, pertaining to three different physiological conditions. Marked differences in certain sub-bands are discernible, which are undetectable in the time-domain alone
