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.
舒张期结构的心动动力学研究显示了其持续的变化。在飞行的第一个月，这些变化包括总舒张期、充盈期和舒张期的时间增加。随后这些参数缩短。等容舒张期缩短，而快速充盈期在整个飞行过程中延长。这些变化似乎与液体重新分布、压力梯度改变以及心脏抽吸活动增强有关。
