在心脏舒张期，心房和心室放松，血液开始流入。
During diastole, the atria and ventricles of your heart relax and begin to fill with blood.
每一次心脏跳动都包含两个基本部分：舒张期以及方式收缩期。
Each heartbeat has two basic parts: diastole and atrial and ventricular systole.
因此，随着时间的推移，心脏在收缩和舒张期之间放松所需要的时间越来越长。
So over time, the heart starts to take a bit longer to relax between contractions and fill back up with blood.
在安慰剂治疗期，心脏收缩压有轻微升高(0.8毫米汞柱)心脏舒张压有轻微下降(0.3毫米汞柱)。
There were slight increases in systolic BP during the placebo phase (0.8 mm Hg) and slight decreases in diastolic BP (0.3 mm Hg).
