心动周期为心脏一次收缩和舒张构成的一个机械活动周期而其中的收缩期就包括心室收缩期。
...过程 以左心室为例,心动周期可分为心室收缩期和心室舒张期(心室内压力、容积、瓣膜、血流): 1. 心室收缩期(ventricular systole): (1) 等容收缩期(period of isovolumic contraction):从房室瓣关闭至主动脉瓣开启的这段时间。

结果表明，应用波生坦后，尽管收缩期和舒张期血压没有变化，收缩末期和舒张期心室体积比例明显升高。
Peak systolic and diastolic strain rates also increased significantly after bosentan treatment, the results indicate, although systolic and diastolic blood pressures were not affected.
