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

以前有风湿性心脏病伴二尖瓣狭窄病史。

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

个位置就是二尖瓣关闭的最佳位置。

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，神经元与二尖瓣细胞触，二尖瓣细胞继续大脑发送信号。

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

因为它主要是因为二尖瓣和三尖瓣关闭的声音，所以它可以在二尖瓣和三尖瓣诊区被清晰到。

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。

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

最，马方综合征也是二尖瓣脱垂的一个危险因素，即二尖瓣在收缩期左心房。

He has a murmur of mitral insufficiency.

他有二尖瓣关闭不全的杂音。

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

左心室发育得不完全。而且二尖瓣连接着左右心室也狭窄得很严重。

Left atrial enlargement is commonly due to mitral stenosis.

左房增大通常是由于二尖瓣狭窄引起的。

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.

进入左心房，血液穿过第二个房室瓣膜，称为二尖瓣，进入左心室。

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

在种情况下，由于是二尖瓣，我们称之为二尖瓣反流。

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 中到的第一个“lub”是由二尖瓣和三尖瓣关闭发出的。

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

然心房收缩，增加压力，所以血液通过二尖瓣进入左心室。

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-心尖部诊最清晰，放射至左腋下。

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与其触，每个代表并识别一种挥发性化学物质。

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。

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，嗅觉轴与另一种神经细胞的树相遇，称为二尖瓣细胞，将信号传递到大脑。

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，三尖瓣和二尖瓣打开；让血液再次充盈心室，段期叫做心脏舒张期。

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，它就会沿着嗅道将其发送到大脑的嗅觉皮层。
