Past medical history of rheumatic heart disease with mitral valve stenosis.

以前有风湿性脏病伴二尖瓣狭窄病史。

That's where the mitral valve closing is best heard.

这个位置就是听二尖瓣关闭的最佳位置。

Oh, the echo tests showed mild mitral stenosis. The tilt test was negative. We're doing E.P. Studies.

哦，超声波检查表明轻微的二尖瓣狭窄。穿刺结果也不好。我们在做EP研究。

After leading to a glomerulus, these neurons synapse with mitral cells, which go on to send signals to the brain.

在通过肾小球后，这些神经元与二尖瓣细胞突触，二尖瓣细胞继续向大脑发送信号。

And because it's basically the tricuspid and mitral valve closing, it's best heard in the tricuspid valve and mitral valve area.

因为主要是因为二尖瓣和三尖瓣关闭的声音，所以可以在二尖瓣和三尖瓣听诊区被清晰听到。

The chambers on the left side are underdeveloped. In addition, the mitral valve, which connects these two chambers, is abnormally narrow.

左室发育得不完全。而且二尖瓣连接着左右室也狭窄得很严重。

He has a murmur of mitral insufficiency.

他有二尖瓣关闭不全的杂音。

Finally, Marfan syndrome is a risk factor for mitral valve prolapse, where the mitral valve pouches into the left atrium during systole.

最后，马方综合征也是二尖瓣脱垂的一个危险因素，即二尖瓣在收缩期时突向左。

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

产生可闻及的收缩期杂音的其他情况包括室间隔缺损和二尖瓣脱垂。

After entering the left atrium, the blood goes through the second atrioventricular valve called the mitral valve into the left ventricle.

进入左后，血液穿过第二个室瓣膜，称为二尖瓣，进入左室。

So the first " lub" that you hear in that lub-DUB is made by the mitral and tricuspid valves closing.

所以你在 lub-DUB 中听到的第一个“lub”是由二尖瓣和三尖瓣关闭发出的。

Left atrial enlargement is commonly due to mitral stenosis.

左增大通常是由于二尖瓣狭窄引起的。

Then the atrium contracts, which increases the pressure, so the blood passes down through the mitral valve into the left ventricle.

然后收缩，增加压力，所以血液通过二尖瓣进入左室。

So for each mitral cell, there are any number of olfactory axons synapsing with it, each representing and identifying a single volatile chemical.

所以对于每个二尖瓣细胞，有任意数量的嗅觉轴突与其突触，每个代表并识别一种挥发性化学物质。

In this case, since it's the mitral valve, we call this mitral regurgitation.

在这种情况下，由于是二尖瓣，我们称之为二尖瓣反流。

He lifted massively heavyweights, and it turned his aortic valve, the one that looks like a Mercedes sign, into a bicuspid double triangular flap.

他能举起巨大的重物，使用类固醇把他的主动脉瓣，那个看起来像梅赛德斯标志的瓣膜，变成了只有一个二尖瓣膜，两个三尖瓣膜。

This holosystolic murmur is best heard at the mitral region -the apex, with radiation to the left axilla.

该全收缩期杂音在二尖瓣部位-尖部听诊最清晰，放射至左腋下。

Inside the glomerulus, the olfactory axons meet up with the dendrites of another kind of nerve cell, called a mitral cell, which relays the signal to the brain.

在肾小球内，嗅觉轴突与另一种神经细胞的树突相遇，称为二尖瓣细胞，将信号传递到大脑。

So, once a mitral cell picks up its signal from an olfactory neuron, it sends it along the olfactory tract to the olfactory cortex of the brain.

因此，一旦二尖瓣细胞接收到来自嗅觉神经元的信号，就会沿着嗅道将其发送到大脑的嗅觉皮层。

Right after the S2 sound, the tricuspid and mitral valves open back up allowing blood to fill up the ventricles again and this period of time is called diastole.

在S2之后，三尖瓣和二尖瓣打开；让血液再次充盈室，这段时期叫做脏舒张期。
