It may also cause the walls of your left ventricle to become stiff and thick, which can change how electrical impulses travel through your heart.

高血压还可以导致左心室壁肥厚、僵硬，由此影响电冲动的传导。

Most heart assist devices support the heart's left ventricle, which pumps oxygen-rich blood to the rest of the body.

大多数的心脏辅助泵装置只支持左心室，它把氧合血泵入身体其他地方。

Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.

心输出量增加，心脏收缩加强能泵更多的血液，心搏量增加，左心室壁变厚(更多肌肉)，心脏对氧气的需要减少。

This extra lead runs from the more easily accessible right ventricle of the heart, out of the heart and into the external vasculature of left ventricle, shocking it from outside the heart.

ECONOMIST: Case history

An LV lead (a thin, coated wire) is placed on the lower left chamber of the heart (the left ventricle) to stimulate the two sides of the heart to beat in synchronization with each other, which helps the heart to beat more efficiently.

But so far as its heart is concerned, he has no more than grasped its right ventricle.
