心室

Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

Results Both left and right ventricular myocardiums were thicken with prominent meshwork of trabecula and deep recesses.

结果 左、右心室肌增厚、疏松，心内膜完整、光滑，向心室肌内凹陷，形成小裂隙，未见其他心脏畸形。

Stored in ventricular myocytes, it is released during ventricular stretch and increased transmural pressure.

由于其储存在心室的心肌细胞，因此当心室舒张期及跨壁压增高时才释放。

To study whether the change of transmural heterogeneity of ventricular repolarization plays an important role in the occurrence and mechanism of ventricular fibrillation in rabbit models with congestive heart failure.

目的 研究充血性心力衰竭模型左心室三层心肌之间单相动作电位的改变，以探讨充血性心力衰竭易发心室颤动的基础电生理机制。

He TandemHeart percutaneous transseptal ventricular assist system is a left ventricular assist device designed to be used as a short-term circulatory support system for procedures not requiring complete cardiopulmonary bypass.

andemHeart经由皮肤跨隔膜心室辅助系统是一种左心室辅助设备，设计作为短期循环支持系统，不需要彻底的心肺通路手术。

一种短期体外循环支持系统能够经由皮肤心脏导管手术，在30分钟内提供心脏辅助支持功能。TandemHeart经由皮肤跨隔膜心室辅助系统是一种左心室辅助设备，设计作为短期循环支持系统，不需要彻底的心肺通路手术。

Double-switch operation is the first choice in correction of DORV with atrioventricular discordance, especially in patients with right ventricular disfunction or tricuspidal regurgitation. If the heart can not be corrected because of combined complicated malformations, the strategy of one ventricular repair can be chosen.

房室连接不一致DORV根治手术应首选double- switch手术，尤其对形态学右心室功能不全和三尖瓣关闭不全者，如果合并多种复杂畸形解剖无法矫治，可选择单个心室的修补方案。

Models based on morphological characteristi cs have been designed to help determine whether early survival is more likely af ter biventricular repair (surgical or balloon aortic valvotomy) or after a singl e ventricle staged palliative surgical strategy.

根据形态学特征已经设计出模型，以决定是双心室修复(外科或球囊主动脉瓣切开术)还是单心室姑息性手术新生儿的早期存活率提高。

If the local ventriculogram recorded during pacing appeared earlier than the V wave of His bundle electrogram and the shape of QRS wave during pacing is similar to that of spontaneous sinus beat,suggest the lead is located at the right ventricular inlet septal region.

若起搏时导线电极记录的局部心室电图的起点比希氏束上的V波提前，且起搏的QRS波与自身窦性搏动的QRS波相似，这个部位便是右心室流入道间隔部位。

One of these four chambers—the left ventricle—contracts most strongly to pressurise the blood.

这四个心室中，左心室收缩最有力，血液流的距离更远。

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。
