氯气(Cl_2)是黄绿色有强烈刺激的气体。氯气能被直接吸收而引起毒作用。在生产及使用氯气的工厂中都可以有氯气逸出。我们对某工厂氯气作业工人133例职业性健康检查中的心电图作分析。以探讨氯气对心血管系统产生的影响。1 资料与方法1.1 资料来源于我院对某工厂氯气作业工人133例,进行心电图检查。男87名,女46名,年龄21～58岁,平均年龄31.10岁,工龄1～37年,平均7.32年。对照组:随机选择不接触有害物质的一般健康体检120名,男77人,女43人,年龄22～60岁,平均年龄35.54岁,工龄1～38年,平均11.9年。1.2 用日本产ECG-6511型心电图机,对受检者作常规9～12
Chlorine (Cl 2) is a strong yellow-green gas. Chlorine can be directly absorbed and cause toxic effects. Chlorine can escape in factories that produce and use chlorine. We analyzed the electrocardiogram (ECG) of 133 occupational health examinations for chlorine workers in a factory. To investigate the impact of chlorine on the cardiovascular system. 1 Materials and Methods 1.1 Data from our hospital on a factory chlorine workers 133 cases, ECG examination. 87 males and 46 females, aged 21 to 58 years old, with an average age of 31.10 years, 1 to 37 years of service, an average of 7.32 years. Control group: randomly selected do not come into contact with harmful substances 120 general health examination, 77 males and 43 females, aged 22 to 60 years old, with an average age of 35.54 years, 1 to 38 years of work, an average of 11.9 years. 1.2 with Japanese-made ECG-6511-type ECG machine for the subjects for routine 9 to 12
