摘　　要：本文应用三维超声心动图系统对20例正常人左室进行了三维重建，并将重建后的左室进行断层和分区，研究其区域射血分数的变化，结果显示，正常人左心室收缩过程中，各部分收缩程度不一致，自心底到心尖部断层射血分数呈现增强趋势，将心脏断层分十二个区域，显示相当于心室前壁的部分区域射血分数较高。We used three-dimensional echocardiography to analyze the regional left ventricular (LV) function of 20uormal persons. The results showed that LV regional EF is gradually increased from the bottom to the apical. The EF ofthe anterior wall is higher than that of the other regions. This primary study suggested that three-dimensionalechocardiography may be used to calculate the regional LV function.
