Uh, she presents with multiple syncopal episodes and ventricular arrhythmia.

噢，她的症状是多次间歇性晕厥并伴有律不齐。

They diagnosed with LVNC which stands for left ventricular noncompaction.

诊为 LVNC，代表左密化不全。

Because of this difference, the left ventricle needs to be stronger; and so the muscular layer of the left ventricular wall or its myocardium is three times thicker than the right ventricle's myocardium.

由于这种差异，左需要更强壮；因此左壁的肌肉，即肌，比右的肌厚三倍。

Ventricular tachycardia is a super-fast heartbeat that affects the organ's ability to pump blood.

性动过速是一种超快的跳，会影响脏的泵血能力。

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.

随着壁扩大，它也挤入了空间，导血液空间缩小，也就是说，除了使缩期功能不全之外，高血压也能导舒张性力衰竭。

A defibrillator is a machine that delivers a targeted, measured amount of electricity to a heart that is either in something called ventricular fibrillation or ventricular tachycardia.

除颤器是一种机器，它会向处于称为颤动或性动过速的脏输送有针对性的、可测量的电量。

And they do that because your ventricles contract to build up pressure and pump blood out of the heart. This high pressure caused by ventricular contraction is called systole.

它们这样做是因为你的缩以增加压力并将血液泵出脏。这种由缩引起的高压称为脏缩。

It's also important to obtain an electrocardiogram, which typically shows a prolonged QT interval, appearance of a U wave, and atrial or ventricular tachyarrhythmias.

电图也很重要，典型表现出长QT间期，出现U波，以及房速或速性律失常。

When we are putting in the defibrillator is when we, when we induced this, this ventricular fibrillation, this very fast heart rhythm.

当我们把除颤器放进去的时候，当我们诱发这个，这个颤动，这个非常快的律。

This happens because there's increased pulmonary congestion while lying down, and in left-sided ventricular heart failure, the pulmonary circulation is already overloaded.

这是因为躺下时肺淤血增多，而左衰时，肺循环已经超负荷。

They were measuring two things: the number of what are called premature atrial contractions and premature ventricular contractions.

房性早搏和性早搏的数量。

The diagnosis of a premature ventricular contraction is based on the ECG, but sometimes a Holter monitor - which is like a continuous ECG monitor used over a few days - is needed to capture the event.

性期前缩的诊基于电图，但有时动态电监护仪（在几天内持续用电图检测）被用来捕捉这个事件。

When it's hooked up, you'll be able to see the rhythm that the heart is in, you'll be able to tell is that person in ventricular fibrillation or ventricular tachycardia.

当它连接起来时，你就能看到脏的节律，你就能分辨出那个人是颤还是性动过速。

You can see what the heart rhythm is and if it's not what you want it to be if it's ventricular fibrillation, then you can go ahead and, and discharge it.

你可以看到律，如颤动的话，那么你可以继续，然后把它松开。

And everything I just described to you — from when the SA node fires to when the last of the ventricular cells contract — takes about 220 milliseconds.

我刚才向你们描述的一切——从 SA 节点触发到最后一个细胞缩——大约需要 220 毫秒。

Then there's the other kind of irregular heartbeat: Premature ventricular contractions are early beats that arise from the lower chambers of the heart.

还有另一种不规则的跳: 性期前缩是由脏下腔(左右)引起的早期跳。

Although it would be unusual for rheumatic heart disease to cause ventricular dysrhythmias, we've still got to check your valves.

也许那对风湿性脏病来说，疾病不太常见，但我们还是要检查下你的瓣膜。

I would like to install a left ventricular assist device. It's a battery-operated machine to help your heart pump.

可以装一个左辅助装置。是个用电池的机器，帮助你的脏来泵血。

An irregular heartbeat, known medically as ventricular tachycardia, is a major cause of sudden heart attacks worldwide.

律不齐，医学上称为性动过速，是全球突发脏病的主要原因。

Premature ventricular contractions are early beats that arise from the lower chambers of the heart.

性早搏是指从脏下产生的早搏。
