摘要
目的探讨不同年龄和性别健康人群QRS额面电轴的特点及变化趋势，并拟定各年龄段QRS额面电轴的平均值及95％参考值范围。方法按国际标准描记2019例不同年龄和性别的健康人十二导联体表心电图，获取其QRS额面平均电轴，进行统计学分析。结果QRS电轴存在明显的年龄差异，随年龄增长向左偏移，而同年龄组男、女之间差异无统计学意义。各年龄段QRS电轴平均值（x^-±s）：0—29d（＋135±29），1—11个月（＋75±33），1—4岁（＋70±31），5—9岁（＋66±29），10-13岁（＋64±28），14—17岁（＋53±31），18—59岁（＋48±30），≥60岁（＋29±32）。结论健康人群QRS电轴存在明显的年龄差异，同年龄组不同性别之间差异无统计学意义，有必要建立与年龄相关的正常值标准，本文所得数据可供拳者。
Objective To investigate the characteristics and changing tendency of frontal QRS axisin healthy population with different ages and sexes, and to establish average values and 95 % reference value range indifferent age groups.Methods Twelve-lead body surface electrocardiogram was performed in 2019 healthy persons（age range, 0 - 94 yr） with different sexes according to international standards. The values of frontal QRS axis were detected and the results were analyzed statistically by computer. Results There was a significant age difference in QRS axis, and QRS axis gradually shifted to the left over the total rang beth in men and women. There was nosignificant sex difference in the same age group. The average values of different age groups were as follows： 0 -29 d（ ＋ 135 ±29）, 1-11 M（＋75±33）,1 -4Y（＋70±31）,5-9Y（＋66±29）,10-13Y（＋64±28）,14- 17Y（＋ 53±31）, 18 - 59Y（ ＋ 48 ± 30）, ≥60Y（ ＋ 29 ± 33）. Conclusion The QRS axis in healthy population shows significant age difference. There is no significant difference between male and female in the same group. It is essential to establish standard of normal values related to ages. The data from this study can be used in clinic for reference.
