目的了解早期复极综合征(ERS)的发生率及其与性别、年龄、心率、导联分布、机体有氧活动量的关系,探讨其临床意义。方法采用整群抽样方法对5000例年龄在20~60岁的健康体检者的心电图进行分析。结果共检出ERS169例,发生率3.38%,其中男160例,发生率4.86%,女9例,发生率0.53%。随着年龄的增加及心率的增快ERS的发生率逐渐降低。轻度劳动强度者发生率2.33%,中度以上劳动强度者发生率4.90%,胸导联ERS发生率高于肢导联及肢导联+胸导联。结论 ERS发生率男性高于女性,并随着年龄的增加及心率的增快而逐渐降低,劳动强度大者发生率也有增加趋势,ERS最常见于胸导联。
Objective To understand the incidence of early repolarization syndrome (ERS) and its relationship with sex, age, heart rate, lead distribution and aerobic activity of the body and to explore its clinical significance. Methods A cluster sampling method was used to analyze the electrocardiogram of 5000 healthy subjects aged 20-60 years. Results A total of 169 cases of ERS were detected, the incidence of 3.38%, of which 160 were male, the incidence of 4.86%, 9 females, the incidence of 0.53%. The incidence of ERS decreases with age and heart rate. The incidence of mild labor intensity was 2.33%, the incidence of moderate labor intensity was 4.90%. The incidence of ERS in the lead was higher than that in the limb leads and limb leads. Conclusions The incidence of ERS is higher in males than in females, and gradually decreases with the increase of age and heart rate. The incidence of ERS also tends to increase. ERS is most commonly found in chest leads.
