目的动态掌握南宁铁路辖区职工心电图异常情况,旨在能早发现、早诊断、早治疗,预防、控制心血管疾病。方法对2005—2009年12027名职工健康检查中的心电图结果进行统计分析。结果2005—2009年心电图异常率为23.50%～26.95%;历年的心电图异常率两两比较,只有2005与2009年异常率差异有统计学意义(P<0.05);各年龄组职工心电图异常率为23.42%～30.69%,且18～30岁和51～60岁年龄组心电图的异常率分别与31～40岁、41～50岁年龄组比较,差异有统计学意义(P<0.05);18～30岁的窦性心律失常检出明显高于其他年龄组(P<0.01);ST段、T波改变随年龄增大而增多。结论心电图异常尤以18～30岁、51～60岁年龄组明显,且低年龄组职工的窦性心律失常多于高年龄组,ST段、T波异常检出率随年龄增大而增高。
Objective To dynamically grasp the anomalies of electrocardiogram (ECG) of employees in Nanning Railway. The aim is to detect, diagnose, treat, prevent and control cardiovascular diseases early. Methods Statistical analysis was performed on the results of electrocardiogram (ECG) in 12,027 workers during 2005-2009. Results The abnormal rate of electrocardiogram in 2005-2009 was 23.50% -26.95%. The abnormal rate of electrocardiogram in previous years was compared with each other only in 2005 and 2009, with significant difference (P <0.05). The abnormal rate of electrocardiogram in all age groups was 23.42% ~ 30.69%. The abnormal rates of electrocardiogram in 18 ~ 30 years old and 51 ~ 60 years old group were significantly different from those in 31 ~ 40 years old and 41 ~ 50 years old group (P <0.05) The 30-year-old sinus arrhythmia detection was significantly higher than other age groups (P <0.01); ST segment, T wave changes with age increased. Conclusions The electrocardiogram abnormality is especially in 18-30 years old group. The age group of 51-60 years old is obvious. And the sinus arrhythmia of workers in the lower age group is more than that of the high age group. The abnormal detection rate of ST segment and T wave increases with age.
