According to the echocardiography,enlarged internal diameter of left ventricle was found in 8 patients and short-axis fractional shortening of left ventricle 5% in 3 patients.Six out of the above 8 patients presented with shortening of accerlerating time,decreasing of accerlerating time/right ventricular ejective time value and moving forward of spectral peak in different degrees.All patients were given antianginal drugs such as β-recepter blockers,nitrate preparations and part by angiotensin converting enzyme inhibitor,diuretics and digoxin,The illncss of 29 patients were gradually controlled within one week.Three patients with AD were complicated by acute left heart failure.No obvious changes in FS of left ventricle were found on echocardiography by bed.

测量肺动脉瓣口血流频谱，左心室内径增大的8例中有6例出现不同程度的血流加速时间缩短，血流加速时间/右心室射血时间比值减小，频谱峰值前移。31例均给予β受体阻滞剂、硝酸酯类等抗心绞痛治疗，部分给予血管紧张素转换酶抑制剂、利尿剂和地高辛，其中29例在1周内卧位型心绞痛逐步得到控制。3例卧位型心绞痛发作时合并急性左心衰竭者，在床旁观察超声心动图，发现左心室短轴缩短率无显著变化，给予利尿剂、减轻前后负荷等治疗，急性左心衰竭得以纠正。

Therefore, the value of two-dimensional echocardiography (2DE) to assess the right ventriciular outflow in 21 children (Aged 2 years to 13 years, mean 6+/- 3.3 years)with TOF was studied using a new subcostal ...

先探查剑下大动脉短轴切面再将探头顺钟向转动并将探头稍前翘，可见升主动脉长轴切面，该切面类似于右心造影右前斜位投影。

The discrete mathematical models of the roundness and cylindricity EST are established; the mathematical models of the generating line straightness, axis straightness, coaxality, circular run—out and total run—out error of the revolution workpiece are put forward and established first based on the EST; the method about how to sample and to process sampling data are given when these models are applied to measure workpleces.

其主要内容是：针对长期以来国内对回转误差运动的有关定义的争论，对回转误差运动的本质进行了讨论，进一步明确了静心与静轴，动心与动轴的概念，并对此进行了数学推导，给出了相应的数学模型；统一了&平动说&和&瞬心说&关于回转轴线的定义，指出了两种学说各自的力学基础和它们的一致性。

The time to peak systolic longitudinal strain and the time to peak systolic radial strain were derived from the LV apical views , and to peak systolic circumferential strain was derived from the parasternal short axis. The standard deviation for time to peak longitudinal、circumferential and radial strain in the 18 segments (LS-SD18、CS-SD18、RS-SD18) and the maximal temporal difference of any two segments(LS-dif、CS-dif、RS-dif)were calculated as a strain-derived dyssynchrony index.
