Before transplantation and 4 weeks after transplantation, all the rats were examined by ultrasonic cardiogram test and haemodynamics test to determine the cardiacfunction.
于细胞移植术前、术后4周，将两组大鼠进行超声心动图、血流动力学检查，测定、比较心功能的指标。
2
Methods: the conditions of the two medicines on controlling premature ventricular beats, improving cardiacfunction and decreasing case fatality rate were compared by random and contrast test.
方法：采用随机对照试验比较两者对室早的控制、心功能的改善及降低病死率的情况。

Cardiac catheterization, standard lung function testing before and after iloprost inhalation, 6-min walk test, World Health Organization functional class, and hemodynamic parameters were monitored.
