1·It was once believed that only diastolic pressure (the "bottom" number) was important, but this is not true.
曾经一度，人们认为只有舒张压(下压值)才重要，但事实并非如此。
2·The systolic part refers to the pressure when your heart is expanded, and the diastolic reading is when your heart is at rest.
收缩部分是指当你的心脏扩展时的压力，舒张的数据读取是当你的心脏放松时产生的压力。
3·A normal blood pressure reading requires a systolic value of 91-119 and a diastolic value of 61-79.
正常的血压读数要求心脏收缩值在91 - 119之间，而心脏舒张值在61 - 79之间。
4·The "bottom" number is the diastolic blood pressure-the pressure while the heart is filling up with blood, getting ready to pump again.
下压值即心脏的舒张压，也就是心脏充溢血液，并准备再次泵出血液时的压力。
5·They're given as systolic over diastolic, like a fraction.
像分数那样收缩的在上舒张的在下给出血压值。
