One value is called " systolic" pressure.

一个值称为“收”。

In fact, systolic blood pressure goes down.

事实上，收会下降。

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

Blood pressure is measured using two values. One value is called " systolic" pressure.

血的测量需要用到两个数值。一个是“收”。

This is your systolic blood pressure.

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

只要你的收 180 以下，舒张 100 以下，你就可以捐献。

Why systolic blood pressure? Why am I mentioning that?

为是收？我为要提这个？

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

高（收）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，收会因为预期的表现而升高。

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

我们还讨论是收和舒张，以及如何测量它们。

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

这被称为单纯收期高或者单纯舒张期高。

Typically, both systolic and diastolic pressures tend to climb or fall together, but that's not always the case.

一般来说，收和舒张是同时上升或者下降的，但也并不总是这样。

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

收期血升高应该120到129mmHg之间，舒张期血则是应该小于80mmHg的区间内。

Sometimes, you can have systolic or diastolic hypertension, when one number is normal and the other is really high.

有时会出现收期或者舒张期高血，即一边的数值很高，但是另一个却处于正常值范围。

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收，导致收性心衰。

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，特指收高于180或舒张高于110。

Systolic's down to 60. Pulse is getting thready.

收降至六十 脉细速。

Systolic pressure 90. Get me a Swan.

收90 给我漂浮导管。

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

产生可闻及的收期杂音的其他情况包括室间隔缺损和二尖瓣脱垂。

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

她心动过速 收九十。
