atria

an opening in the atrial septum, or dividing wall between the two upper chambers of the heart known as the right and left atria.

During each normal heartbeat, the muscle cells in the upper chambers of the heart, the atria (AY-tree-uh), contract.

在心脏正常跳动时，心房的肌肉细胞会首先收缩，这样血液就会从心房压入心室。

An atrial septal defect is unlikely to produce a loud murmur because of the minimal pressure differential between the atria.

房间隔缺损不产生明显心脏杂音，因为心房之间压力差很小。

The interior of the heart is divided into four chambers: upper right and left atria and lower right and left ventricles.

内部的心脏分为四个商会：上左，右心房和较低的左，右心室。

After conducting research among staff, the bank built the tower around garden atria that let in natural light.

在雇员中进行调查后，该银行围绕着一座花园中庭建造了该大厦，以便接受自然光照。

Within the building, air movement can be directed by roof form, thermal flues, and atria controlled by louvred openings.

Atria have become much more common as integral components of commercial building designs over the last twenty years.

在过去的二十年里中庭作为商业建筑设计中不可或缺部分已愈加普遍。

First, the two upper chambers of the heart, called atria (AY-tree-uh), contract.

首先，心脏上不得两个腔室（心房）收缩。

The catheter is quickly pulled back through the hole, into the right atrium, enlarging the hole, allowing blood to mix between the atria.

经过这个孔快速向回拽导管至右心房内，扩大了这个孔，使血液在心房之间可以混合。

Atrial septal defect is a hole in the division between the heart atria.

心房间隔缺损指心脏房室间隔上有洞，很少见于犬。

The study of its electrophysiological mechanism and molecular etiology supplies plenty of academic basis to therapy of atria fibrillation.

研究房颤的电生理分子病因学方面的机制，将为其治疗提供较多理论基础和依据。

In a healthy heart, electrically conductive muscle cells fire for each contraction of the atria and ventricles [see illustration].

对正常心脏而言，心房与心室每一回收缩，都会有导电的心肌细胞兴奋放电（见右图）。

Healthy valves open and close in coordination with the pumping action of your heart's atria and ventricles.

健康瓣膜的开合会严密配合心房与心室的泵血动作。

These smaller atria admit sunlight into the main atrium at various times throughout the day.

这些较小的心房接纳阳光到主房在不同时期的一天。

In HE stain, myocardial hypertrophy, severe myolysis and extensive fibrosis in the interstitial space of the atria were found in AF group.

HE染色发现心房颤动患者的心房有肌溶解、心肌肥厚及广泛的间质纤维化改变。

The right coronary and left circumflex are especially prone to artifact due to their proximity to the right and left atria, respectively.

由于右侧冠状动脉和左旋支由于靠近右侧和左侧心房，更容易出现伪影干扰。

Catheter ablation of the AV junction permanently interrupts conduction from the atria to the ventricles.

房室结消融结点的导管消融永久性妨碍从心房到心室的传导。

The scar tissue stops atrial fibrillation by interfering with chaotic electrical signals that cause the atria to contract irregularly.

瘢痕组织通过阻断紊乱的电传导而终止房颤，该紊乱的电传导会使心房不规律收缩。
