单纯性肥胖儿童的发病率可高达3％～17％。为此,我们对36例单纯性肥胖症患儿作心脏检测,并与同龄正常儿童相比较。1 对象及方法单纯性肥胖儿童36例,男21例,女15例,年龄7岁～12.5岁,平均10.8岁。正常儿童在年龄、性别和身高上与病例组配对.在二维超声指导下做M型检查。检测参数有:左室舒末径(LVDD)、左室收末径(LVSD)、室间隔舒末厚度(STD)、室间隔收末厚度(STS)、左室后壁舒末厚度(LVPWD)和收末厚度(LVPWS)、左室心肌重量(LVMW)和左室舒末容积(LVDV)、每搏输出量(SV)、每分输出量(CO)、左室心肌平均周径向心缩短率(MVCF)、射血分数(EF)、左室室壁增厚率 The incidence of simple obesity children can be as high as 3% to 17%. To this end, we conducted 36 cases of simple obesity in children with heart testing, and compared with normal children of the same age. 1 Subjects and Methods Simple obesity in 36 children, 21 males and 15 females, aged 7 to 12.5 years, mean 10.8 years. Normal children were matched with the case group by age, sex and height, and M-type examination was conducted under the guidance of two-dimensional ultrasound. The parameters of LVDD, LVSD, STD, STS, LVPWD, LVPWS, LVMW and LVDV, stroke volume per minute (SV) and output per minute (CO) were measured. The mean radial center of left ventricular myocardium was shortened Rate (MVCF), ejection fraction (EF), left ventricular wall thickening rate
