目的通过对受职业性健康检查的647例山钢集团菜芜钢铁新疆有限责任公司接尘作业工人心电图进行分析,了解工人心电图异常分布情况,为心血管疾病的防治提供参考。方法对647例山钢集团菜芜钢铁新疆有限责任公司接尘作业工人进行职业性健康检查,对常规心电图检测结果进行分析。结果分析的647例受检工人中,心电图异常者112例,异常率为17.31%;其中,≥40岁年龄组的心电图异常多,异常率为17.29%;不同年龄组间心电图异常率比较,差异有统计学意义(x2=14.34,P<0.05)。结论山钢集团菜芜钢铁新疆有限责任公司接尘作业工人的心电图及血压异常率随着年龄的增加而增高。
Objective To analyze the electrocardiogram of workers exposed to dust in 647 cases of occupational health check-up by Wuwei Iron & Steel Xinjiang Xinjiang Co., Ltd. to understand the abnormal distribution of workers’ electrocardiogram and provide references for the prevention and treatment of cardiovascular diseases. Methods Occupational health examinations were conducted on 647 workers who took dust from the steel-making company of Wuwei Iron and Steel Co., Ltd. in Wuhu, Shanxi Province. The results of conventional electrocardiogram examination were analyzed. Results Among the 647 cases examined, 112 cases had abnormal electrocardiogram (ECG), the abnormality rate was 17.31%. Among them, the abnormal electrocardiogram was more than 40 years old and the abnormal rate was 17.29%. The difference of ECG abnormalities among different age groups was significant There was statistical significance (x2 = 14.34, P <0.05). Conclusion Electrocardiogram (ECG) and abnormal blood pressure of dust-exposed workers in Shanwei Group’s Wuhu Iron and Steel Xinjiang Co., Ltd. increased with age.
