In fact, systolic blood pressure goes down.

事实上，缩会下降。

Why systolic blood pressure? Why am I mentioning that?

为什么是缩？我为什么要提这个？

This is your systolic blood pressure.

这就是你缩。

Usually left-sided heart failure is caused by systolic (or pumping) dysfunction.

通常左侧力衰竭是因为缩（或泵送）功能障碍。

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缩和舒张，以及如何测量它们。

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

只要你缩在 180 以下，舒张在 100 以下，你就可以捐献。

The top number, called systolic, represents the force with which your heart pumps blood into the blood vessels.

高（缩）是指脏将液泵入管力量。

When we're gearing up to do something hard, systolic blood pressure goes up in anticipation of the performance.

当我们准备做一些困难事情时，缩会因为表现而升高。

Systolic pressure 90. Get me a Swan.

缩90 给我漂浮导管。

Her systolic blood pressure would rise.

她缩会上升。

B.P.'s 60 systolic. Oxygen is low.

缩六十 氧很低。

She's tachy. B.P. of 90 systolic.

她动过速 缩九十。

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

另一个源性因素是严重全身性高，特指缩高于180或舒张高于110。

Other conditions that cause audible systolic murmurs include ventricular septal defect and mitral valve prolapse.

产生可闻及缩杂音其他情况包括室间隔缺损和二尖瓣脱垂。

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

尽管缩性衰是左侧力衰竭最主要病因，舒张性力衰竭或充盈障碍也有可能发生。

More demand and reduced supply means that some of the ventricular muscle starts to have weaker contractions —leading to systolic failure.

需求增大而供减少，意味着一些肌开始虚弱地缩，导致缩性衰。

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

以毫米汞柱（mmHg）记录，先记录缩，然后记录舒张。

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

重度子痫前患者缩可达到160毫米汞柱以上，舒张达到110毫米汞柱以上。

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

这被称为单纯缩高或者单纯舒张高。

Elevated systolic blood pressure is considered between 120 and 129 mmHg and less than 80 mmHg on the diastolic side.

缩升高应该在120到129mmHg之间，舒张则是应该在小于80mmHg区间内。
