本文在126例带有大血管的胎儿、婴幼儿和儿童的正常心脏上测量了主动脉口、升主动脉、主动脉峡、降主动装和肺动脉口的内径,并就其与胸围及坐高的关系进行了回归分析。126例心脏中,胎儿心脏50例,胎龄自妊娠5月至9月;婴幼儿和儿童心脏76例,其中生后3天至1岁者30例,1岁以上至3岁者21例,3岁以上至5岁者14例,5岁以上至8岁者8例,8岁以上至11岁者3例。126例胎儿、婴幼儿和儿童的胸围在13-66cm之间,坐高在16-76cm之间。回归分析的结果求得了上述各部位的内径与胸围及坐高关系的回归方程。1.主动脉口内径与胸围呈正相关,r=0.907,b=0.228,回归方程y=0.228x-2.044mm(r为相关系数,b为回归系数,y表示主动脉口内径的估计值,单位为毫米,x代表胸围,单位为厘米,以下同)。2.升主动脉内径(主动脉瓣上方1厘米处)与胸围呈正相关,r=0.943,b=0.257,y=0.257x-2.350mm。3.主
In this paper, the aorta, ascending aorta, aortic isthmus, descending aorta and pulmonary artery were measured on the normal heart of 126 fetuses, infants and children with large blood vessels. The relationship between the regression analysis. 126 cases of heart, 50 cases of fetal heart, gestational age from May to September of pregnancy; 76 cases of infants and children’s heart, including 3 days after birth to 1 year old in 30 cases, 1 year old to 3 years old in 21 cases, There were 14 cases from the age of 3 to 5 years, 8 cases from 5 years old to 8 years old and 3 cases from 8 years old to 11 years old. 126 cases of fetus, infants and children bust in the 13-66cm, sitting between 16-76cm high. The results of regression analysis obtained the above-mentioned parts of the inner diameter and chest and sit height relationship regression equation. 1. Aortic diameter and chest circumference were positively correlated, r = 0.907, b = 0.228, the regression equation y = 0.228x-2.044mm (r is the correlation coefficient, b is the regression coefficient, y represents the aortic orifice diameter of the estimated value, unit Mm, x on behalf of the chest, in centimeters, the same below). 2. The ascending aortic diameter (1 cm above the aortic valve) is positively correlated with the chest circumference, r = 0.943, b = 0.257, y = 0.257x-2.350mm. Lord
