【摘要】 目的了解性别、年龄对0￣12岁儿童Tp-Te间期的影响,建立该年龄段儿童Tp-Te间期的参考值范围。方法 320例心电图正常的0￣12岁儿童作为研究对象,并按照年龄分为0～3岁、4～6岁,7～9岁,10～12岁组,各组内分男女亚组。测量研究对象12导联心电图Tp-Te间期,取每例研究对象V2～V4导联最大Tp-Te间期为研究指标,并用Bazett公式对Tp-Te间期进行校正。对不同性别、不同年龄组间Tp-Te间期和校正Tp-Te间期进行比较,并求其Tp-Te间期的参考值范围。结果各组内不同性别间心率、Tp-Te间期和校正Tp-Te间期的比较显示,组间均无显著性差异;相同性别Tp-Te间期在0～3岁组和4～6岁组间、7～9岁组和10～12岁组均无显著性差异,而0～3岁、4～6岁组显著低于7～9岁组和10～12岁组;校正Tp-Te间期在女性各年龄组间无显著性差异;在男性10～12岁组高于0～3岁组和4～6岁组,其他各年龄组间无显著性差异;Tp-Te间期正常值参考范围为:0￣6岁49.3￣112.3ms,7￣12岁62.9￣119.2ms;校正Tp-Te间期正常值参考范围为:0￣6岁63.6￣141.2ms,7￣12岁71.5￣141.3ms;结论 0～12岁儿童性别对Tp-Te间期和校正Tp-Te间期没有影响,随年龄增长,Tp-Te间期延长而校正Tp-Te间期变化不大。Tp-Te参考值上限为0￣6岁112.3ms,7￣12岁119.2ms;校正Tp-Te参考值上限为0￣12岁141.3ms。更多还原

【Abstract】 Objective To comprehend how sex and age influence the electrocardiographic Tp-Te interval for 0~12 year-old children, and to definite normal value of Tp-Te interval. Methods 320 healthy children with normal electrocardiogram were divided to 4 groups, and man and women subgroup. Tp-Te interval was measured in 12 leads electrocardiogram, and the maxium Tp-Te interval of V2~V4 were adopted and corrected with Bazett’s formula (Tp-Tec). Results Heart rate, Tp-Te and Tp-Tec were not different between women and man in every group (p>0.05). Tp-Te was not different between 0~3 year-old group and 4~6 year-old group (p>0.05) and between 7~9 year-old group and 10~12 year-old group (p>0.05) in women or man; Tp-Te of 0~3 year-old group and 4~6 year-old group was less than that of 7~9 year-old group and 10~12 years-old group (p<0.01) in woman and man; Women’s Tp-Tec was not different among all groups(p>0.05), Men’s Tp-Tec was more in 10~ 12 year-old group than that of 0~3 year-old group, and 4~6 years-old group (p<0.05), but among other group, men’s Tp-Tec was not different (p>0.05). The normal values of Tp-Te was as follows: 49.3~112.3ms in 0~6 years-old, 62.9~119.2ms in 7~12 year-old; the normal Values of Tp-Tec was as follows: 63.6~141.2ms in 0~6 year-old, 71.5~141.3ms in 7~12 year-old. Conclusion In children of 0~12 year-old, sex did not influence Tp- Te. Tp-Te prolonged with ageing, but Tp-Tec had no change. The top limit of Tp-Te normal values was definite 112.3ms in 0~6 years-old and 119.2ms in 7~12 years-old, the top limit of Tp-Tec normal values was definite 141.3ms in 0~12 years-old.更多还原
