本文分析了420例四乙基铅汽油作业工人的心电图,发现心电图异常占43.5%(183例),比对照组高两倍;15年以上工龄组明显高于5年以下的工龄组;有症状、体征的中毒者也明显高于对照组,说明心电图异常与症状、体征基本一致。作者提议接触者的心电图异常可以作为慢性四乙基铅汽油中毒的诊断指标之一。 In this paper, we analyzed the electrocardiogram of 420 workers with tetraethyl lead gasoline and found that the ECG abnormality accounted for 43.5% (183 cases), which was twice as high as the control group. The workers in the 15-year service group were significantly older than those in the 5-year service group. , Signs of poisoning were significantly higher than the control group, indicating abnormal ECG and symptoms, signs are basically the same. The authors suggest that contact with ECG abnormalities can be used as a diagnostic indicator of chronic tetraethyl lead poisoning.
