title: [Dynamics of the diastolic phase structure in an 140-day space flight].
abstract: The kinetocardiographic study of the diastolic structure demonstrated its consistent changes. In the first flight month they included an increased time of total diastole, filling and diastasis periods. Later these parameters shortened. The phase of isometric relaxation was reduced whereas that of rapid filling was enlarged throughout the flight. These changes seem to be associated with fluid redistribution, shift in the pressure gradient and enhancement of the sucking activity of the heart.
