Abstract
The seismocardiogram (SCG) is a complex, nonstationary signal used for pathological analysis of cardiac vibratory activity. This corresponde nce reports the results of multiresolution wavelet decomposition of SC G's for a normal male subject, pertaining to three different physiolog ical conditions. Marked differences in certain sub-bands are discernib le, which are undetectable in the time-domain alone.
