心动

from January 1996 to January 2006,425 patients with atrioventrieular nodal reentrant taehyeardia were included .

回顾性分析我科1996年1月至2006年1月采用射频消融治疗的阵发性房室结折返性心动过速患者425例。

BACKGROUND: In some types of pediatric supraventricular tachycardia,reentrant mechanisms are sensitive to enhanced vagal tone.

背景：在小儿室上性心动过速的一些类型中，折返机制对增高的迷走神经张力很敏感。

Background: Fetal and neonatal atrioventricular reentrant tachycardias can be life-threatening but resolve in most cases during the first year of life.

背景：胎儿和新生儿房室折返性心动过速可危及生命，但在大多数情况下生命中第一年这种危险得到解决。

If this changes appear in any part of the reentrant circle, reentry will be interrupted due to the loss of match.

如这一改变出现在折返性心动过速的折返环路上的任何部位即可因传导时间和不应期的失匹配而使折返运动终止。

Arterial baroslope was acquired by line regression of R-R interv a l from electrocardiogram and changes in arterial systolic blood pressure.

用心动周期和动脉收缩压变化量的线性回归斜率来反映动脉压力感受器反射敏感度。

This study measured the isovolumic contraction time , isovolu-mic relaxtion time and ejection time of CCP group and normal contrast group. Late,tei index was calculated, relationship between Tei index and LV function index such as ejection fraction ,the ratio of transmitral peak velocity at early diastole to transmitral peak velocity at late diastole etc.

本研究通过对正常对照组与肺心病病例组使用频谱多普勒超声心动图测量ICT、IRT、ET时间计算Tei指数，观察肺心病左心室Tei指数变化并分析其与超声测定的心功能指标EF、E/A等相关性，探讨Tei指数评价肺心病左心室整体功能的价值。

Other imaging studies to consider include ultrasound to evaluate for renal angiomyolipomas or renal cysts, as well as cardiac CT or echocardiogram to evaluate for rhabdomyoma.

其他的可行的影像检查包括超声以明确肾血管平滑肌错构瘤或肾囊肿、心脏CT或超声心动图以明确横纹肌瘤。

Of the methods of assessing heart function in patients with cor pulmonale, radionuclide ventriculography is more valuable one than others such as chest roentgenography, electrocardiography and echocardiography.

放射性核素检查克服了胸片、心电图、超声心动图等常规检查的一些缺点，是检查肺心病病人心功能的一个较有前途的手段之一。

It has long been known that the apex and base of the heart rotate about the left ventricular longitudinal axis in different directions during the cardiac cycle,resulting in a twisting,or torsional motion.

心动周期中心尖及心底沿左室长轴向不同方向旋转，引起心脏扭曲或扭转运动。

For business experience, Samson Charlie, is the most important ",".

对于创业的心得，孙查理认为，最重要的是"心动"。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
