心室的

The left ventricular meets the optimal efficiency principle at systolic state,we utilize the differ-ential geometry and differentiable dynamics to analyse the model and inverts it to the linear space for optimal control theory solution of optimal efficiency of ejective blood-flow which meets the physiology of optimal efficiency.

结果 在左心室的收缩最优效率原则时候，可应用微分几何与微分动力学数学分析法，将模型转换为线性空间下最优控制理论求得射血流量。

In order to make a thorough use of the anatomical and functional information derived from cardiac magnetic resonance images, the epicardium and endocardium of the left ventricle should be extracted in advance.

为了充分利用心脏核磁共振图像(magnetic resonance image，简称MRI)中关于左心室的解剖和功能信息，必须先分割左室壁内、外膜。

The pulmonary ale is seen on top of the infundibulum of the right entricle.

右心室的动脉圆锥上方可看到肺动脉瓣。

Recent evidence indicates that the cholinergic innervation of the left ventricle is functionally very important in some mammalian species.

近年来的研究显示在一些哺乳动物的心脏上，胆碱能神经在心室也有分布，且对左心室的功能有重要的调控作用。

A deformable model is used to reconstruct the shape of the LV: first, the dynamic equation governing the surface deformation is deduced; secondly the image planes are mapped to the reconstruction coordinate system. From the slices data, the external force exerted on the surface is defined and the elastic force of the surface is constructed by mean curvature of the deformation surface. Finally, a level set method is applied to solve the dynamic equation for LV shape.

为了重建左心室的形状，使用基於形变模型的方法：首先建立变形曲面的动力学方程；再将成像坐标系中的图像平面映射到重建坐标系，根据图像数据构造外力，使用平均曲率构造变形曲面的弹性力，然后用水平集数值解法求解动力学方程以重建左心室的表面。

It proves that the simulation reasonably reproduces the mechanical function of the left ventricle during systole.

结果表明，仿真基本再现了收缩期左心室的动力学特性。

But in China, we still can not solve the problem of single ventricle.

但是在中国，我们仍然还不能解决单心室的问题。

When in the short axis view with the papillary muscles and chordae tendineae in view place the M. mode cursor between the papillary muscles and obtain an M-mode trace of cardiac function.

当心室乳头肌与其腱索呈现在短轴图像时，将M模式的屏幕游标放在心室的乳头肌之间，同时藉由M模式探测心脏的功能。

However, when AV interval was shorter than 80 msec and longer than 180msec, there was reduction of LVOTG, yet the CO was also reduced. The results showed that the hemodynamic improvement must depended on the state of pre-excitation of ventricle as well as the optimal left ventricular filling.

且在AV间期为100至120毫秒时出现最佳血液动力学效应，而AV间期在小于80毫秒、大于180毫秒时，虽有左室流出道压力阶差的降低，但心输出量均有下降，提示血液动力学的改善必须依赖右心室的提前激动状态及最佳的左心室充盈。

Patients after right-sided pneumonectomy had an abnormal low R end-diastolic olume of 99 ± 29 mL together with a normal L function.

右侧肺切除的患者其右心室的舒张期末容积异常低99 ± 29 mL，而左心室的功能是正常的。

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。
