左转

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。

1 The approach of LVB cannulated by passed retrograde across the aortic valve can be performed easily and reduce LV pre-load and LV work, as well as cardium oxygen consumption significally; 2 This LVB can improve coronary artery perfusion and cardiac function while AOMP can be maintained after LAD occlusion; 3 There has a potential impariment effect on the right ventricular function with excessive amount BFR (over 85%) during LVB, particularly in the present of myocardial ischemia; 4 Roller pump is not suited for a prolonged bypass because of significant damage to the blood system.

由此我们得出以下实验结论：经外周动脉逆行左室置管转流方法操作简便、迅速。能明显减少左室前负荷，减少左室作功，降低心肌耗氧量；能维持严重心脏缺血后的平均动脉压，改善冠脉循环灌注和左室功能，具有临床应用的可行性。85%以上转流率对缺血心脏的心功能有潜在的损害效应。以75%左右转流率较为合适。转子泵不适宜用作长时间转流。

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。

From the Oakland Airport:Turn left on Doolittle Drive and go straightfor about 5 miles.

从奥克兰机场出发：在杜利特高速上向左转，并直行约5英里。

I kept to my described strategy of "riding north and sometimes turning left," which was serving well enough.

我一直对我的描述战略&，有时骑北左转&，这是服务方面做得不够好。

On the same day the whole French army, after reaching in its spasmodic rush as far as Murat's position, seemingly with the object of giving battle, suddenly, with no apparent cause, turned off to the left to the new Kaluga road, and began marching into Fominskoe, where Broussier had before been alone.

十月十日，多赫图罗夫前往福明斯克途中，抵达阿里斯托沃村，停止前进，准备正确执行上级命令的时候，就在这同一天，好像得了疯病一样，全部法国军队开到了缪拉的阵地，好像准备要打一仗，可是突然又无缘无故地向左转到新卡卢日斯卡雅大路，进驻原先只有布鲁西埃驻扎在那里的福明斯克。

Then take a left to get to the bank.

向左转，就到银行了。

Do I turn left at the bank?

我要在银行左转吗？

It's first left after the bank.

过了银行在第一个路口左转。

No,don't turn left at the bank.

不，不要在银行那儿左转。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
