摘　　要：为研究胎儿、新生儿和婴幼儿的心血管血流动力学变化特点，本文运用二维和多普勒超声心动图检测了三组各瓣口血流。结果显示，胎儿组右心占优势而左室顺应性低下，肺动脉阻力高，存在心内分流；新生儿组肺动脉阻力降低，左室顺应性开始转变，但左室舒张功能尚不完善；婴幼儿组左心占优势，左右室顺应性转变为正常，肺动脉阻力进一步降低。In order to study the differences of the cardiovascular dynamics of the fetus newborn and in-fant,we selected 56,32 and 63 cases of each for Doppler echocardiographic research.The results showed that,in the fetal group,the right heart played a dominante role for cardiac activity resulted in a default compliace of the left ventricle(LV),pulmonary resistance(PA)was higher than aorta and a shunt flow presented; in newborn group, on the contrary,PA was lower,LV compliance improved,buf the diaxtolic function of the LV was still not in its full play;in infant group,LV and RV compliance steped up to normal,while PA further reduced.
