Both of the septal and anterior regions are served by the left anterior descending artery.

心脏前壁和室间隔区域接受左前降支的血液供应。

A ventricular septal defect is when this lower wall—the ventricular septum— has a gap in it after development.

室间隔缺损就是位于心脏下方的室间隔，在发育之后存在一个缺口。

Atrial septal defect, but you feel it's an emergency?

- 房间隔缺损，但您觉得这是紧急情况？

Now, sometimes, individuals might have an atrial septal defect, a small opening between the right and left atrium.

同时，某些人患有房间隔缺损的，即右心房与左心房之间有一个小的缺口。

Atrial septal defect is a defect within the upper two chambers of the heart.

- 房间隔缺损是心脏上部两腔内的缺损。

The lead now has an uninterrupted view of septal depolarization.

该导联现在可以不间断地发生间隔去极化。

The arrhythmia was caused by a minor septal defect, which means there's a very small hole between two of the heart's chambers.

你心律不齐是由轻微的心房中隔缺损引起的，也就是说在你两个心室中间有一个小洞。

In LEFT bundle branch block septal depolarization is REVERSED, from right to left, giving a negative wave in V1.

左束支传导阻滞时，室间隔从右向左反向去极化，V1导联呈负波。

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。

If you have a ventricular septal defect, again, your heart is going to have to start working a lot harder.

如果室间隔缺损，同样，心脏将不得不开始更加努力地工作。
