心耳

Objective To study blood flow wave patterns of left atrial appendage in patients with sinus rhythm.

目的 研究窦性心律左心耳血流频谱的类型，评价相应的血流动力学。

The morphologic feature of these cells corresponded to that of auricle cardiomyocytes and the cell activity was good.

结果：急性分离的细胞中绝大部分为杆状，形态结构符合心耳肌细胞的特征，且细胞活性好。

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。

Objective To evaluate the predictive value of left atrial appendage function in success of electrial cardioversion in patients with nonvalvular atrial fibrillation, and observe the course of the recovery of LAA systaltic function.

目的 阐明左心耳功能对非瓣膜病心房颤动患者电转复成功率的预测价值，且对电转复后左心耳收缩功能恢复过程进行观察。

In the Embolic Protection in Patients with Atrial Fibrillation trial, researchers compared the current standard of therapy, anticoagulation with warfarin, to a fabric-covered expandable nitinol cage known as the WATCHMAN, which blocks blood clots that typically form in the left atrial appendage, an outpouching of the left atrium.

在房颤患者的血栓保护试验中，研究者比较了目前应用华法林抗凝的治疗，以及一种名为WATCHMAN的左心耳封闭系统（可防止左心耳内血栓的可膨胀镍钛装置）的治疗效果。

The causes were right auricle injury by violently placing a electric catheter to it (n=2),coronary sinusinjury by violently placing a electric catheter to distal CS (n=3) and by intracardiac electric defibrillation using electric catheter electrodes of high right atrium and CS as current loop(n=1),perforations of right atrial wall (n=3) and left atrial wall(n=2) by sliding up of the transseptal set,and perforation of left auricle by misplacing the mapping catheter of left superior pulmonary vein to it (n=1). 10 cases of acute tamponade occurred during operation, and 2 after operation.12 patients were treated successfully with urgent pericardiocentesis, and no patients required emergency surgery.

引起心包填塞的原因有：①放置电极导管至右心耳时用力过大致右心耳损伤(2例)；②放置电极导管至冠状静脉窦时，因导管不易进入远端而用力过大致CS损伤(3例)；③心内电除颤时采用高位右房和CS电极作回路，致CS损伤(1例)；④房间隔穿刺系统向上滑动穿破右房(3例)和左房(2例)；⑤放置左上肺静脉标测电极时导管误入左心耳致其穿孔(1例)。10例急性心包填塞出现于术中，另2例术后发生。12例患者经紧急心包穿刺引流均成功治愈，无1例需外科急诊手术。

LAA mechanical activity prior to ECV is highly related to maintenance of sinus rhythm in NVAF, and LAA "stunning" developed a thrombogenic milieu. Patients with atrial fibrillation should be given full anticoagulation to prevent thrombogenesis in left atrial and LAA.

NVAF患者电转复前左心耳收缩功能与窦性心律的维持高度相关；转复后左心耳&顿抑&，出现了血栓易于形成的条件，故对此类患者电转复后应给予足够的抗凝治疗，预防左房与左心耳血栓形成。

Methods: A new self- manufactured LAA occluder was implanted into the LAA through a transseptal catheter in 20 dogs.

用自行研制的新型左心耳封堵器经导管封堵20只犬的左心耳。

There's another form of cardio that works much the same way, though it affects the emotional heart rather than the one made of auricles and ventricles.

有另一种心脏锻炼，道理也基本一样。不过，它所影响到的是一颗情感的心而不是由心耳和心室组成的那颗心。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
