The highest value of aortic blood pressure in systole. 指心室收縮主動脈壓達到的最高值。

Next, your heart’s ventricles contract (an event called ventricular systole) and pump blood out of your heart. 接下來，心室收縮（稱為“心室收縮期”）將血液泵出心臟。

Your heart’s ventricles then contract (ventricular systole), pumping blood out of your heart. 接下來，心室收縮（心室收縮期）將血液壓出心臟。
