查询词典 atrial

Methods: Atrial tissue was obtained from the right appendage during open surgery in 25 patients with RHD. The mRNA of ACE and ERK2 and AT1R was semi-qualified by reverse transcription-ploymerase chain reaction and normalized to the glyceraldehyde 3-phosphate dehydrogenase. Western blotting analysis was employed to examine the expression of ACE and ERK and AT1R. Atrial collagen volume fraction was detected by Masson's stain.

25例风心病二尖瓣狭窄接受外科手术者，手术时取右心耳处心房组织500mg，通过逆转录—聚合酶链反应技术，以GAPDH为内参照测量ACE、AT1R、ERK2的 mRNA变化，用Western Blotting了解ACE、AT1R、ERK在蛋白水平表达的差异，经免疫组织化学了解胶原纤维容积分数改变情况。

The pacing of pacemaker can change the normal exciting sequence of heart and can lead to interatrial,interventricular,and atrioventricular asynchronism,thus result in adverse hemodynamic effect and consequent atrial mechanichal and electrical reconstitution.This is the main mechanism of developing atrial fibrillation.

心脏起搏改变了正常心脏激动顺序，使双房间、双室间及房室间激动不同步，带来不利的血流动力学效应，导致心房机械重构和电重构，这是房颤发生的主要机制。

Biatrial and right ventricular triple chamber pacinmg is founded through implanting coronary sinus lead to pace left atrium on the base of conventional right atrial and right ventricular dual chamber pacing,which realizes the synchrony of electrical activities in both two atriums,remove interatrial conduction block and interatrial reentry,and prevent and treat atrial tachyarrhythmias induced by interatrial conduction block.

在常规右房、右室双腔起搏的基础上，植入冠状窦电极起搏左房，建立双房右室三心腔起搏系统，实现双房电活动的同步化，消除房间传导阻滞和房间折返，防治由房间传导阻滞引起的房性快速性心律失常。

Objective To study the characters of L type calcium current of atrial isthmus,and to investigate the mechanism of arrhythmias related to atrial isthmus.

目的 研究心房峡部L型钙电流的特性，探讨心房峡部参与心律失常的机制。

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.

将6对双极记录电极分别缝于高位左、右和低位左、右心房外膜以及左、右心耳，采用心脏程序期前刺激法(S1S2)，分别测量基础起搏周长为300、250和200ms时的心房有效不应期、AERP频率适应性、AERP离散度、房颤诱发率及平均持续时间等电生理指标。

Changeable D wave type, characterized by temporary enlargement of D wave during changes of posture or raising leg test, appears in left atrial myxoma, atrial septal defect, etc.

变动D波型，特点是变动体位或抬腿试验时，D波暂时增大，说明左房压一过性增高，见于左房粘液瘤及房间隔缺损等。

Methods To investigate the clinical results,from January 2002 to June 2007,15 cases diagnosed left atrial myxoma by Doppler echocardiography were operated under cardiopulmonary bypass.Mitral valve proplasty were operated on one patien and tricuspid valve proplasty were operated on five patients,atrial septal defect were repaired on two patients.Results One case died before operation,the others got a successful results,no death happened on preoperative period and operative course.

回顾分析2002年1月至2007年6月我院收治的15例左心房黏液瘤病例，术前均经彩色超声心动图确诊，均在体外循环下行黏液瘤摘除术，同期行二尖瓣成形术1例，三尖瓣成形术5例，房间隔缺损修补术2例。

The membranes may be held in place over the ostium of the atrial appendage or fill the inside of the atrial appendage.

隔膜可以固定在心房附件口上，或者填充心房附件内部。

The primary end point was the incidence of atrial fibrillation. The second end points were New York Heart Association cardiac function class, changes in left atrial and left ventricular end-diastolicdiameters, as well as left ventricular ejection fractionmeasured by echocardiography.

主要研究终点为房颤的发生率，次要终点为心功能分级及超声心动图检查指标(左心房内径、左心室舒张末期内径、左心室射血分数)。

Both thrombophlebitis and pyemia are typical examples of hypercoagulatory states caused by inflammation.In fact,inflammation had been showed as an important reason that lead to thrombotic events in a lot of studies of atherosclerosis and heart failure.Further investigations have showed a prothrombotic state with blood hypercoagulation,platelet activation,damaged atrial endothelium and atrial blood stasis in AF,while these changes are due to the AF itself,or coexistent cardiovascular risk factors remains a matter of debate.

虽然房颤时高凝状态和血小板功能激活是非常明确的，是造成房颤血栓形成的重要原因之一(其他两个原因包括心房血流淤滞和内皮功能损害)，但是房颤高凝状态和血小板功能激活与炎症水平的关系，尽管对指导采取何种预防血栓形成的治疗策略意义很大，目前已有的研究较少涉及这方面，国内外几乎没有相关的研究报告。

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。
