Methods From September 1990 to August 2004, 7 cases of DORV with atrioventricular discordance received surgical therapy. The age ranged from 3 years to 7 years. Surgical managements included: ventricular septal defectrepair and homograft connected the morphologic left ventricle with pulmonary artery in 3 cases, double-switch in 2 cases, modified Fontan in 2 cases.

1990年9月至2 0 0 4年8月对7例房室连接不一致的DORV患者施行根治手术治疗，年龄3～7岁，其中形态学左心室与肺动脉心外管道连接和室间隔缺损修补术3例，double- switch手术2例，改良Fontan手术2例。

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。

Methods To analyze the operation ways of atrioventricular canal defects,fousing on the repair of ostium prium,atrial and ventricular septal defect,the correction of reflux in artio-ventricular valve and the protection for the injury of conducting bundle.

方法分析全组32例心内膜垫缺损病人的手术方法和诊疗过程，重点讨论了瓣叶裂和房室间隔缺损的修补，房室瓣返流的纠正和防止传导束的损伤。

It is well established that Cav1.2 encoded L-type calcium channel is prevailing component in cardiac system, while Cav1.3 encoded one dominant expressed in neuron and neuroendocrine cell. However, our and others' previous works have shown that Cav1.3 encoded LTCC was also found in the heart tissues, especially in pacemaking cells of sina atrial node, atrioventricular node and atrium.

最初人们认为心脏中的 L 型钙通道仅包括α1C（Cav1.2），但后来发现α1D（Cav1.3）在心脏中也有表达，并且优势表达于窦房结、房室结和心房，加之发现它在比较低的膜电位（－60~50mv）激活而且α1D基因敲除小鼠表现出窦性心动过缓和房室传导阻滞，所有这些都表明α1D 在维持正常的心脏节律中发挥着至关重要的作用。

Objective To investigate the characteristics of atrioventricular nodal reentrant tachycardia and its classification.

目的 探讨典型的房室结双径路引起的房室结折返性心动过速可激动间隙的特点及其分区。

Background: Fetal and neonatal atrioventricular reentrant tachycardias can be life-threatening but resolve in most cases during the first year of life.

背景：胎儿和新生儿房室折返性心动过速可危及生命，但在大多数情况下生命中第一年这种危险得到解决。

Atrioventricular valves lie between the atria and ventricles, and semilunar valves are located at the bases of the two large vessels leaving the heart.

房室瓣放在心房和心室和半月瓣之间位于离开心脏的二艘大船的基地。

The first heart sound is caused by the closure of the atrioventricular valves and so marks the beginning of ventricular systole.

第一心音的原因是关闭房室瓣膜等标志着心室收缩。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
