本文运用心脏超声对30例健康成人的主动脉根部运动特点进行观测,发现主动脉根部的上下位移幅度大于前后摆动,两者均较动脉内径变化明显得多,在此基础上对15例充血性心肌病作了对比观察,发现其主动脉根部几种运动的幅度均明显降低,其中下降幅度仅5.7±1.2mm(P<0.01)。据此认为,主动脉根部运动反映了心脏的功能状态。 In this paper, 30 cases of healthy adults were observed by aortic root movement characteristics and found that the displacement of the aortic root up and down more than before and after the swing, both were significantly more than the diameter of the artery, on this basis, 15 cases of congestive Cardiomyopathy was observed and compared, and found that the aortic root amplitude of several movements were significantly reduced, of which the decline was only 5.7 ± 1.2mm (P <0.01). Therefore, the aortic root movement reflects the functional status of the heart.
