We also talked about what systolic and diastolic blood pressure are, and how they're measured.

我们还讨论了什么是收缩压和舒张压，以及如何测量它们。

As long as your blood pressure is below 180 systolic and 100 diastolic, you may donate.

只要你的收缩压在 180 以下，舒张压在 100 以下，你就可以捐献。

The bottom, called diastolic, is a measure of the resistance to the blood flow in the body's blood vessels.

而低压（舒张压）是人体血管中血流阻力的测量方法。

Even though systolic failure is most common in left-sided heart failure, diastolic heart failure or filling dysfunction can also happen.

尽管收缩性心衰是左侧心力衰竭最主要病因，舒张性心力衰竭或充盈障碍也有可能发生。

The second reading is your diastolic blood pressure, which is the pressure in your arteries when the ventricles are relaxed.

第二个读数是你的舒张压，这是心室放松时动脉中的压力。

An example of diastolic murmurs is aortic valve regurgitation.

舒张期杂音的一个例子是主动脉瓣反流。

Another cardiogenic cause is severe systemic hypertension - specifically a blood pressure that is greater than 180 systolic or 110 diastolic.

另一个心源性因素是严重的全身性高血压，特指收缩压高于180或舒张压高于110。

Blood pressure is recorded in millimeters of mercury (mmHg) with systolic pressure written first, followed by diastolic pressure.

血压以毫米汞柱（mmHg）记录，先记录收缩压，然后记录舒张压。

In severe preeclampsia, systolic blood pressure can be 160 mmHg or greater and diastolic blood pressure can be 110 mmHg or greater.

重度子痫前期患者的收缩压可达到160毫米汞柱以上，舒张压达到110毫米汞柱以上。

This is referred to as isolated systolic hypertension or isolated diastolic hypertension.

这被称为单纯收缩期高压或者单纯舒张期高压。
