本文研究了57例常见先心病(PDA、VSD、ASD、TOF)患儿及60例正常儿童心导钠微分环(CADL).结果显示:先心病CADL环体缩小,形态无明显变异,C相、E相和总环体的面积及校正值较对照组减小,TOF组时间指数及校正值较对照组增大.四种先心病变化趋势相同,但右→左分流较左→右分流变化更为显著.CADL能反映先心病血液动力学变化,对判断心功能、指导治疗具有一定价值.
In this study, 57 cases of common heart disease (PDA, VSD, ASD, TOF) and 60 normal children cardiac sodium differential ring (CADL) were studied.The results showed that: CADL ring of the congenital heart narrowing, no obvious morphological changes, C phase , The area and the correction value of E phase and total annulus decreased compared with the control group, while the time index and the correction value of TOF group increased compared with the control group.The trend of the four CHDs was the same, but the changes of right → left shunt → left → right shunt changes More significant.CADL can reflect the hemodynamic changes in congenital heart disease, to determine the cardiac function, guiding treatment has a certain value.
