Abstract: Objective To summarize the electrocardiogram(ECG)features of 1 814 disabled soldiers by means of statistical analysis of ECG results of them. Methods ECG features of retired disabled soldiers from July 1, 2013 to April 30, 2015 in Shanghai Shuangyong building were collected.There were 1 814 cases, including 1 702 males and 112 females.They were divided into young group(aged from 18 to 44 years, n=216), middle-aged group(aged from 45 to 64 years, n=785)and old group(aged more than 64 years, n=813).The type and proportion of abnormal ECG were summarized, and the relationship between abnormal ECG, age and basic diseases was analyzed. Results There were 603 cases(33.2%)with abnormal ECG.The incidences in groups of young, middle-aged and elderly disabled soldiers were 14.8%, 30.3%, and 40.9%, respectively.There was no statistically significant difference in abnormal ECG rate between men and women(P＞ 0.05).The incidence of abnormal ECG from high to low were ST-T changes(33.5%), tachyarrhythmia(29.0%)and bradyarrhythmia(27.9%), left atrial/ventricular hypertrophy(23.1%), old myocardial infarction(4.5%), limb lead low voltage(1.8%), right atrial/ventricular hypertrophy(1.7%)and acute myocardial infarction(0.3%).Compared to subjects without underlying diseases, subjects with basic diseases were more likely to have abnormal ECG(P＜0.05), and the ratio from high to low were chronic obstructive disease, heart disease, hypertension, diabetes and stroke. Conclusion The incidence and types of abnormal ECG of disabled soldiers are similar to that of other groups.
