STEP 3 Put some plants on your desk. One study found that when workers had greenery nearby, they were 12 percent quicker at a given computer task and their systolic blood pressure lowered by one to four points.

办公桌上放置一些植物。一项调查发现，当工作人员附近有绿色植物时，他们在特定的计算机任务中效率高12%，他们的心脏血压会降低1至4个点。

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；这使动得以保持形状，以及承受、平衡收压和舒张压。

One value is called " systolic" pressure.

一个值称为“收压”。

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

血压的测量需要用到两个数值。一个是“收压”。

This means that as the heart muscle wall enlarges, it crowds into the ventricular chamber space, resulting in less room for blood, meaning that in addition to contributing to systolic dysfunction, hypertension also can cause diastolic heart failure.

随着心壁扩大，它也挤入了心室空间，导致血液空间小，也就是说，除了致使收期功能不全之外，高血压也能导致舒张性心力衰竭。

These two numbers give your nurse a sense of how your arteries and ventricles are doing, when they're experiencing both high pressure — the systolic -- and low pressure — the diastolic.

这两个数字可以让你的护士了解你的动和心室在经历高压（收压）和低压（舒张压）时的情况。

If it's a simple... if it's a simple thing like what's the differential for aortic stenosis, i. e. injection systolic murmur, there's just four points here.

如果这是一个简单的...如果这是一个简单的内容，比如主动的鉴别诊断，即注射收期杂音，这里只有四个要点。

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，特指收压高于180或舒张压高于110。

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

高压（收压）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，收压会因为预期的表现而升高。

This is your systolic blood pressure.

这就是你的收压。

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

只要你的收压在 180 以下，舒张压在 100 以下，你就可以捐献。

In fact, systolic blood pressure goes down.

事实上，收压会下降。

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。

The first number is your systolic blood pressure — essentially the peak pressure, produced by the contracting ventricles that push blood out to all of your tissues.

第一个数字是你的收压——也就是峰值压力，由收的心室产生，将血液推出到你所有的组织。

Why systolic blood pressure? Why am I mentioning that?

为什么是收压？我为什么要提这个？

So if your systolic blood pressure is too low, that could mean that, say, the volume of your blood is too low — like, maybe because you've lost a lot of blood, or you're dehydrated.

所以如果你的收压过低，这可能意味着，比如说，你的血容量过低——比如，可能是因为你失血过多，或者脱水了。

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。

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压和舒张压，以及如何测量它们。

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.

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