查询词典 atrial

Background: Atrial septal defect is the most common congenital heart diseases .Exactly assessment of the site, shape, size and anatomic relation of the defect with its surrounding structures is essential for the clinical management of the patient.

研究背景：房间隔缺损(Atrial septal defect，ASD)的发病率在各种先天性心脏病(Congenital heart diseases ，CHD)中居首位，准确诊断缺损的部位、形态、大小及与周围组织的毗邻关系很大程度上决定了治疗方法的选择及治疗效果。

Atrial distension rather than change in atrial pressure has been suggested as a principle mediator of ANP realease.

Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

The research is to approach the relation between every indicatrix with atrial fibrillation's happening and development through investigating the change of the gene expression of cluster of differentiation 11b (CD11b) on polymorphoneucler, interleukin-6(IL-6) and tumor necrosis factor-αin right atrial appendage altered in patients with chronic atrial fibrillation.

本研究通过观察CD11b、IL-6和TNF-α在窦性心律及伴有慢性心房颤动的风湿性瓣膜病患者心肌中基因表达的改变，来探讨各指标与AF发生发展的关系。

RT-3DE shows clearly full view of the primary atrial tumor than two-dimensional echocardiography and obvious image differences between atrial myxoma and malignant atrial tumor. It is a convenient, quick and precise modality for diagnosing primary atrial tumor and may be of significant clinical value for the diagnosis of primary atrial tumor.

RT-3DE比二维超声心动图更清晰显示原发心房肺瘤全貌形态，黏液瘤与恶性心房肿瘤图像特征差别明显，RT-3DE是诊断原发心房肿瘤简便、快捷和准确的检查方法，RT-3DE对原发心房肿瘤具有重要临床诊断价值。

The first special techniques was the method of tightening slip knot predisposed on atrial septal via veins. The suture with loop was placed on the atrial septum incision which will be closed during the decannulation. The loop was hitched up by the drawn-string via vein and tied with two or three slip knot after inserting left atrial cannulas.

第一种特殊技术是一种经静脉应用心导管将右房内预置的滑结拉紧的方法，其要点是术中在要闭合的房间隔切口处做缝合并留好线套，穿上牵引线经左锁骨下静脉引出，插左房管后打2或3个滑结，拔管后应用这种特殊技术将滑结拉紧，并拆除牵引线。

Methods The rabbits were anesthetized and removed the heart. The left atrium was isolated and fixed on the atrial perfusion system and paced by electrical stimulation. Atrial pulse pressure was measured via a pressure transducer connected to the intra-atrial catheter and recorded on a physiograph.

方法将大耳白兔耳缘静脉注射乌拉坦（20 mg/kg）麻醉后，立即开胸取出心脏，剥离左心房迅速固定在心房灌流装置上，并给予适宜的电刺激使心房搏动，利用生理记录仪持续记录相关药液影响下的心房搏动压的变化，并读取每搏输出量。

Results after eight- week rapid atrial pacing,the aerpd was significantly decreased,the intra-atrial conduction time was shortened and the atrial muscle conduction velocity was significantly increased in the treatment group compared with control group.

结果 起搏8周后，与对照组比较，治疗组aerp离散度减小，心房内传导时间缩短，心房肌传导速度加快。

The incidence of intra-atrial aberrant conduction post-premature atrial systole, premature junctional systole, premature ventricular systole, pararrhythmia, short duration of supraventricular tachycardia and atrial fibrillation were 63.7%, 14.3%, 11.0%, 7.7%, 2.2%, 1.1%, respectively. Of all the cases, 74.9% suffered from cardiovascular disease, 62.8% were patients older than 60 years with cardiovascular disease, 12.1% were complicated by heart failure.

结果 总发生率为0.43%，房性早搏后引起者占63.7%，交接性早搏后占14.3%，室性早搏后占11.0%，并行心律后占7.7%，短阵性室上速后占2.2%，短阵性心房颤动后占1.1%。74.9%有心血管疾病，60岁以上老年心血管病患者占62.8%，12.1%合并有心衰。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
