Abstract
The paper deals with an analysis of relationship between heart rate described by a sequence of cardiac interbeat
intervals and mechanical activity of heart represented by a sequence of systolic forces. Both the quantities were determined
from seismocardiograms recorded from healthy subjects under two different experimental conditions. The method of the
linear feedback baroreflex approach originally developed in [1], [2] and [3] was applied for the analysis. Different character
of obtained results in comparison to those described in [1], [2] or [3], is explained by differences between frequency
properties of the recorded sequences of the systolic forces and values of systolic blood pressure
