心房

Most patients recovered with normal function of atrioventricular valves by follow up with ECG after extirpating the tumor;⑤myxoma had lower recurrence rate and longer recurrence interval, and malignant tumor had higher recurrence rate and shorter recurrence interval.

原发心房肿瘤ECG图像特征及规律性明显，ECG对原发心房肿瘤有特异性诊断价值，但最后确定肿瘤性质必须依靠病理诊断。

The number of pulmonary vein and maximal dimension of the PV ostia were determined by each imaging modality. Results 59 patients(83.1%) had typical pattern of pulmonary veins with four separate orifice for bilateral upper and lower pulmonary veins, respectively.

结果 CT共显示290根肺静脉， 59例(83.1%)患者有典型的左上、下肺静脉和右上、下肺静脉4个心房开口。9例(12.9%)有单独心房开口的副肺静脉。3例(4%)为左肺静脉共干。

ResultsThe autorhythmicity of the isolated right atriums were inhibited after treated with DSS. Moreover, their contraction scale,contraction velocity and relaxation speed were significantly reduced in a dose-dependent manner.

结果3'大豆苷元磺酸钠可降低豚鼠离体右心房的自律性，明显降低豚鼠离体右心房的收缩幅度、收缩速度、舒张速度，且具有明显的剂量依赖性。

The results showed that the IR nerves were found in the ventricle, atrium,venous sinus and the aortic valve; besides, a lot of ganglions and single neurons were also observed in right atrium.

结果发现 SP- IR纤维分布于心室、心房、静脉窦、主动脉瓣处；右心房见散在阳性细胞及神经节。

BACKGROUND: Previous researches have proved that both atrial natriuretic polypeptide and 5-hydroxytryptamine (5-HT) exist in the same endocrine granule of enterochromaffin cell. However, whether ANP may promote or inhibit synthesis and secretion of 5-HT needs to be further studied.

背景：作者前期研究证实心房钠尿肽和5-羟色胺共同存在于胃肠嗜铬细胞的同一分泌颗粒中，那么心房钠尿肽对5-羟色胺的合成与分泌是促进还是抑制，目前仍处于研究阶段。

Methods From Jan. 1999 to July 2004, the clinical data of 12 patients with Scimitar syndrome were analyzed retrospectively, 10 patients underwent repair by intra-atrial baffles approach, one patient by connecting scimitar vein and left atrium with artificial blood vessel under cardiopulmonary bypass, and one patient by directly reimplanting the scimitar vein to left atrium without cardiopulmonary bypass.

回顾分析我院1999年1月～2004年7月12例镰刀综合征患者的临床资料，10例采用经典房内通道技术；1例采用体外循环，用人工血管将镰刀静脉与左心房相连；1例在非体外循环下直接将镰刀静脉吻合在左心房。

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。

Results In univariate analysis, atrial fibrillation, huge left atrium, long course of left-sided valve diease, degradation of left heart function （LVEF 〈0.50）, tricuspid rheumatic pathological change, enlarged right atrium and single mitral valvar disease were significant risk factors of TR devdopment.

结果单因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长、左心功能低下（LVEF〈0.50）、右房增大（≥50mm）、三尖瓣风湿性病变及单纯二尖瓣病变是继发性TR进行性加重的危险因素；多因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长及三尖瓣风湿性病变是继发性TR进行性加重的危险因素；远期随访显示，B组心功能改善明显优于A组，TR程度明显低于A组，C组术后无1例发生TR。

The atrial ganglionated plexuses formed by ganglia and nerve fiber bundles were connected with each other by nerve fiber bundles on the right and left atrial surface; the...

但是在光镜下未发现心房神经节丛和心室神经节丛之间有神经纤维束相连。这个形态学发现支持把心房神经节丛和心室神经节丛区分为两个相对独立的功能单位的概念。

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。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
