摘要
目的通过比较Cornell指数与Sokolow指数在儿童心电图中诊断左心室肥厚(LVH)的性能来评估两者的诊断价值。方法分析我院自2008至2010年的儿童患者共1082例,根据年龄分为1月～3岁组(男232人,女184人),3～13岁组(男198人,女143人)及13～17岁组(男186人,女139人),每组根据超声心动图测定的左心室内径(LVD)分为正常组和LVH组,计算Cornell指数和Sokolow指数的诊断特异性、灵敏性和准确率。结果在1月～3岁年龄组中,Cornell指数的男女的特异性、灵敏性及准确率均高于Sokolow指数;在3～13岁年龄组及13～17岁年龄组中,特异性差别不大,均>95%,但Cornell指数的灵敏性及准确率高于Sokolow指数。结论 Cornell指数在儿童心电图中诊断LVH的性能要高于Sokolow指数。
Objective To appraise the diagnosis value of Cornell index and Sokolow index by com- paring their performance in pediatric electrocardiogram for left ventricular hypertrophy. Methods One thou- sand and eighty two cases of children inpatient from 2008 to 2010 in our hospital were divided into three groups： one months to three years old（232 cases in male and 184 eases in female） ,three years old to thirteen （198 cases in male and 143 cases in female）,thirteen to seventeen （186 cases in male and 139 cases in fe- male）. Each group was divided into normal group and LVH group according to left ventricular diameter （LVD） detected by echocardiogram. Sensitivity ,specificity and accurancy of Cornell index and Sokolow index were calculated. Results In the group of one months to three years, the sensitivity , specificity and accuran- cy of Cornell index were higher than Sokolow index for both sexes. There was no significant difference of the two indexes in the other two groups（〉0.95）, but the sensitivity and aecurancy of Cornell index were higher than Sokolow index for both sexes in the later groups. Conclusion The effect of Cornell index is more effec- tive than Sokolow index in pediatric electrocardiogram diagnosis for left ventricular hypertrophy.
