摘　　要：目的评判肥胖儿童的心血管功能状态。方法选择30例肥胖儿童以及50例年龄、性别相匹配的正常体质量儿童进行运动平板测试,比较两组间运动耐量、运动过程达亚极量心率的运动时间,以及持续T波电交替(TWA)的发生率。结果与正常体质量儿童相比,肥胖儿童运动耐量明显降低,且其达亚极量心率的运动时间也明显缩短,差异有统计学意义(P均<0.01);肥胖儿童持续TWA发生率明显增高,差异也有统计学意义(P<0.01)。结论肥胖儿童常伴发心血管功能障碍,提示在儿童时期就应关注肥胖可能导致的心血管损害。ObjectivesTo assess the cardiovascular function in obese children.MethodsA total of 30 obese children and 50 age- and sex-matched normal weight children were enrolled and treadmill test was performed. Exercise tolerance, the time to target heart rate and continuous T-wave alternans （TWA） during treadmill test were compared between two groups. ResultsCompared with normal weight children, the exercise tolerance was decreased and the time to target heart rate was shortened, while the incidence of continuous TWA was increased in obese children and there was signiifcant difference between two groups （P〈0.01）.ConclusionsObesity may lead to cardiovascular dysfunction in childhood which should be concerned.
