健康青年右心室优势心电图分析

Evaluating electrocardiogram of right ventricular dominance in healthy youth

目的探讨健康青年右心室优势心电图的临床意义。方法测量235例大学生心电图平均心电轴和右心室优势导联的R/S比值,分析电轴右偏、V1导联R/S≥1及其他右心室优势的相关参数。结果235例中电轴右偏39例(16.60%),V1导联R/S≥125例(10.04%),两者同时出现8例(3.40%),其他右心室优势的相关参数值几乎均低于正常成人标准。结论部分健康青年可出现右心室优势心电图表现,属正常变异。

Objective To assess clinical significance of electrocardiogram of right ventricular dominance in healthy youth. Methods Mean axis of QRS, R/S ratio and other parameters of right ventricular dominant leads were analyzed in 235 healthy university students. Results Right axis deviation presented in 39 students （16.60%）, R/S≥ 1 in V1 presented in 25 students （10.04%） and both right axis deviation and R/S ≥ 1 in V1 presented in 8 students （3.40%）. Other parameters reflecting right ventricular dominance were almost lower in youth than in adults. Conclusion Electrocardiographic findings of right ventricular dominance may be presented in healthy young people.
