This is your systolic blood pressure.

这就是你的收缩压。

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

通常左侧心力衰竭是因为收缩期（或泵送）功能障碍。

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

高压（收缩压）是指心脏将血液泵入血管的力量。

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。

Systolic pressure 90. Get me a Swan.

收缩压90 给我浮导管。

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

心动过速 收缩压九十。

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

收缩压六十 血氧很低。

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。

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

一般来说，收缩压和舒张压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。

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缩，导致收缩性心衰。

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

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

When diagnosing preeclampsia, hypertension is defined as a systolic blood pressure of 140 mmHg or greater or diastolic blood pressure of 90 mmHg or greater.

在诊断子痫前期时，高血压的定义为收缩压大于等于140毫米汞柱或舒张压大于等于90毫米汞柱。

Stage 1 hypertension is between 130 and 139 mmHg on the systolic side, and between 80 and 89 mmHg on the diastolic side.

一期高血压收缩压在130-139mmHg之间，舒张压在80-89mmHg之间。

Now in addition to systolic heart failure, you’ve also got diastolic heart failure, which is where the heart’s squeezing hard enough but not filling quite enough.

除收缩性心衰外，还有舒张性心力衰竭，指的是心脏收缩功能正常，但是在舒张期充盈受损。

Stage 2 hypertension is defined as anything that is 140 mmHg or higher on the Systolic side and 90 mmHg or higher on the diastolic side.

二期高血压就是收缩压高于140mmHg、或者舒张压高于90mmHg。

These guys are really stretchy, kind of like Spandex and this is what allows these arteries to keep their shape, as well as absorb and even-out the systolic and diastolic pressures.

它们很有弹性，有点像Spandex弹力衣；这使动脉得以保持形状，以及承受、平衡收缩压和舒张压。

A normal ejection fraction is around 50-70%, between 40-50% would be borderline, and anything about 40% or less would indicate systolic heart failure because the heart is only squeezing out a little blood each beat.

正常的射血分数大约是在50-70％间，40-50％会是底线，任何低于40%的射血分数指示收缩性心力衰竭，也就是说在心脏在每次搏动中只输出了少量血液。
