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

The combined contraction of the atria and ventricles is a heartbeat.

心房和心室的这一系列动作合称为一次心跳.

Yet on maximal vagal stimulation, both atria and ventricles come to a standstill.

然而,以最大刺激作用于迷走神经时, 心房和心室都停搏.

Both atria are thinwalled muscular chambers.

Conclusions-Atrial arrhythmias occurred in 15 % of adults with congenital heart disease.

结论 — 我们的研究结果显示15%的先天性心脏病成人患者会并发房性心律失常.

Howeer, ejection fraction and left atrial volume index stayed the same.

但是, 射血分数及左房容积仍然不变.

Each heartbeat has two basic parts: diastole and atrial and ventricular systole.

每一次心脏跳动都包含两个基本部分: 舒张期以及方式收缩期.

Objective : To investigate the relation between embolic event and left atrial thrombosis.

目的: 探讨栓塞事件与左房血栓之间的关系.

Carotid sinus pressure has little or no effect on the atrial rate in atrial flutter.

压迫颈动脉窦对心房扑动时的心房率几乎不起作用.

The vagus nerves have an inhibitory action on atrial pacemakers.

迷走神经对心房起搏点有抑制作用.

Flattening of the right atrial border is also seen in constrictive pericarditis.

右心房缘变平亦见于缩窄性心包炎.

Atrial fibrillation is the most common disorder of cardiac rhythm.

心房颤动是最常见的心律失常.

Conclusion: Xin An Di Bi Ji is ideal in preventing atrial fibrillation.

结论: 中药心安宁滴鼻剂是一种比较理想的可用于防治房颤的药物.

Here we reported a 25-year-old woman who presented with paroxysmal atrial fibrillation.

在此我们报导了一位二十五 岁 的女性,她就诊时表现为突发性的心房颤动.

Atrial fibrillation is a familiar arrhythmia in clinic. Anticoagulation is more important.

心房颤动是临床上常见的心律失常, 抗凝较为重要.

Background-Safety and efficacy limit currently available atrial fibrillation ( AF ) therapies.

安全性和有效性限制了现有的房 颤 治疗.

Warfarin is the better choice in the anticoagulative treatment of atrial fibrillation.

而华法令是目前心房颤动抗凝较好的选择.

Objective To analyse retrospectively clinical features of 156 patients with atrial fibrillation.

目的回顾性分析156例患心房纤颤的住院病例临床特点.

The supraventricular arrhythmias in this group included APB, JPB, PSVT, Atrial Flutter and Atrial Fibrillation.

本组室上性心律失常包括房性早搏 、 交界性早搏 、 阵发性室上性心动过速 、 心房扑动和颤动.

Atrial fibrillation ( Af ) is one of the most common arrhythmias.

心房颤动 ( 房颤 ) 是最常见的心律失常之一.

AIM : To study the effects of cycloprotobuxine-A ( Cyc-A ) on atrial fibrillation.

目的: 研究环原黄杨星A ( Cyc -A ) 抗心房纤颤的作用.
