目的：探讨10~20岁青少年早复极的发生率及早复极心电图特征。方法于2013年10月，随机抽取宁夏、内蒙古自治区10~20岁在校学生3000例，心电图检查，筛选出早复极图形，对比早复极阳性组与阴性组间相关指标的差异。结果获得有效心电图3000份，118份表现早复极心电图，早复极发生率为3.9%，男性发生率为5.9%，女性发生率1.5%，男性发生率高于女性（P＜0.05）。早复极心电图中J点抬高在V2~V4、Ⅱ、Ⅲ、aVF导联发生最多；早复极形态以顿挫形和切迹形为主。早复极阳性与早复极阴性组人群的BMI无统计学差异（P＞0.05）；2组心电图P波间期、PR间期、QRS间期均无统计学差异（P＞0.05）；而2组RR间期、QTc值具有统计学差异（P＜0.05），阳性组RR间期大于阴性组，阳性组QTc值小于阴性组。结论早复极发生率为3.9%，男性发生率高于女性。早复极图形中J点抬高在V2~V4、Ⅱ、Ⅲ、aVF导联发生最多；顿挫形与切迹形发生最多。早复极阳性组心电图RR间期大于阴性组，阳性组QTc值小于阴性组。

[Absract]Purposes: To investigate the prevalence of the Early Repolarization (ERP) in adolescents of 10 to 20 years old and to study the characteristic of ERP .Methods 3000 adolescents from the students in Ningxia and Inner Mongolia Autonomous Region were screened by ECG from October, 2013. The physical examination about height, weight, blood pressure and the family history were obtained. Diagnostic criteria for ERP is J point elevalation with QRS notching or slurring at least 0.1 mV in more than 2 consecutive leads in 12-lead ECG. 3000 valid ECG from age 10 to 20 years old were obtained. The total prevalence of ERP is 3.9%, The prevalence of male is 5.9% and the female is 1.5%. Based on the analysis of ECG, J point elevation of ERP occurs mainly at V2-V4,Ⅱ, Ⅲand aVF leads. The patterns are mainly nothing and slurring . BMI, systolic pressure and diastolic pressure between the ERP- positive group and ERP- negative group shows no statistical differences. The P-wave duration, PR interval, QRS interval between the two groups shows no statistical differences. But the RR interval and QTc interval between the two groups presents statistically different.Conclusions The prevalence of ERP is 3.9%, Male’s prevalence is 5.9%,and female’s is 1.5%. J point elevationof ERP mainly occurs in V2-V4,Ⅱ,Ⅲ,and aVF leads. The patterns are mainly nothing or slurring. The RR interval and QTc of ECGs shows statistical differences between the two groups.
