In fact, systolic blood pressure goes down.

事实上，缩压会下降。

Why systolic blood pressure? Why am I mentioning that?

为什么是缩压？我为什么要提这？

This is your systolic blood pressure.

这就是你的缩压。

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

通常左侧心力衰竭是因为缩期（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.

只要你的缩压在 180 以下，舒张压在 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.

高压（缩压）是指心脏将血液泵入血管的力量。

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的事情时，缩压会因为预期的表现而升高。

Systolic pressure 90. Get me a Swan.

缩压90 给我管。

Her systolic blood pressure would rise.

她的缩压会上升。

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

缩压六十 血氧很低。

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

她心动过速 缩压九十。

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

另一心源性因素是严重的全身性高血压，特指缩压高于180或舒张压高于110。

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

产生可闻及的缩期杂音的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。

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

需求增大而供血减少，意味着一些心肌开始虚弱地缩，致缩性心衰。

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.

这被称为单纯缩期高压或者单纯舒张期高压。

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

缩期血压升高应该在120到129mmHg之间，舒张期血压则是应该在小于80mmHg的区间内。
