1·Objective to evaluate left ventricular systolic function based on mitral regurgitation during systole.
目的探讨根据收缩期二尖瓣反流评价左室收缩功能的价值。
2·The result showed that ck could correctly color encoding of the left ventricular wall motion throughout systole, therefore ck could provide the images directly and obtain the result quickly.
结果显示，CK技术能对整个收缩期的左室壁运动进行正确的彩色编码，显示方法直观，判断结果迅速。
3·Results The surfaces of the prolapsed mitral valves showed rough and accompanied with abnormal tendinous chordae , and their bodies projected into left atrium during systole.
结果收缩期脱垂的二尖瓣表面粗糙并向左房膨出，可伴有腱索异常。
