Another term for this is having a reduced " preload" which is the volume of blood that's in the ventricle right before the ventricular muscle contracts.

形容这一现象的术语是为心脏前负荷减少，指的是心室在心肌收缩前的血量。

Blood now moves from the right ventricle through the pulmonary semilunar valve, which is the valve that separates the right ventricle and the lungs.

现在，血液从右心室通过肺半月瓣移动，肺半月瓣是将右心室和肺分开的瓣膜。

Deoxygenated blood from the body enters the heart at the right atrium and passively travels past the tricuspid valve to fill the right ventricle.

来自身体的脱氧血进入右心房的心脏，被动地通过三尖瓣注入右心室。

Of these, the most useful are leads V1 and V6 as they are best located to detect impulses moving between the left and right ventricles.

其中，最有用的是V1和V6导联，因为它们最适于检测在左、右心室之间移动的脉冲。

If the ectopic focus originates in the left ventricle, the wave will depolarizing the left ventricle first and then the right ventricle, which produces a QRS complex that looks like a right bundle branch block.

如果异位起搏点源于左心室，这个波将会首先除极左心室，然后是右心室，这会产生类似于右束支阻滞的一个QRS波群。

If the ectopic focus originates in the right ventricle, the wave will depolarize the right ventricle first and then the left ventricle, and this produces a QRS complex that looks like a left bundle branch block.

如果异位起搏点源于右心室，这个波将会首先除极右心室，然后是左心室，这会产生类似于左束支阻滞的一个QRS波群。

The path the electrical impulse takes to the bottom of the heart is called the atrioventricular bundle, also known by the more rad name, the bundle of His, where it branches out to the left and right ventricles.

电脉冲到达心脏底部的路径被称为房室束，还有个更棒的名字——希斯氏束，它在那里分支到左心室和右心室。

When this right ventricle contracts, it forces the pulmonary semilunar valve to open, allowing a rush of blood into the pulmonary trunk, which is the large artery that leaves the right ventricle.

右心室收缩时，它会迫使肺半月瓣打开，从而使血液涌入肺动脉，后者是离开右心室的大动脉。

It's then delayed just slightly as it goes through the atrioventricular or AV node, before it passes through the Bundle of His and to the Purkinje fibers of the left and right ventricles, causing them to contract as well.

之后，它在通过房室结时发生了短暂的延搁，而后通过房室束以及左右室的浦肯野纤维，使左右心室收缩。

The tip struck the soft part of Czigo's abdomen just below the sternum, slammed upward with terrible force over the liver and through the diaphragm to crush the right ventricle of the man's heart.

尖端击中了 Czigo 胸骨下方柔软的腹部，以可怕的力量向上撞击肝脏并穿过隔膜，压碎了这个人心脏的右心室。
