The upper receiving chambers of the heart are the atria. The lower pumping chambers are the ventricles.

室间隔将两心室分开，房间隔将两心房分开。

It is also called broken-heart syndrome. The heart's main pumping chamber weakens and suffers a temporary disruption so that it cannot pump blood properly.

这种疾病也被称为“broken-heart syndrome”。心脏的主泵血腔减弱并遭受“暂时性的破坏”，因此无法正常泵血。

When your heart contracts, it's fair to think of it as your ventricles contracting, because they are the primary pumping chambers of your heart.

心脏收缩时，可以把它看作是心室收缩，因为它们是心脏的主要泵血室。
