Analysis of Abnormal ECG in the Workers Exposed to Noise in a Diesel Engine Factory

  • 摘要:
    [目的] 探讨柴油机厂噪声作业工人心电图异常改变。

    [方法] 采用现场环境检测和职业健康体检的方法,对柴油机厂从事噪声作业工人332人的心电图进行分析,并与293名对照组进行比较。

    [结果] 接触组工人心电图异常率明显高于对照组(P < 0.01)。心电图异常主要表现为窦性心动过缓、窦性心律不齐、ST-T改变及分支传导阻滞。接触组工人各工龄段心电图异常率均高于对照组,心电图异常率在初期最明显,不随工龄的增长而增加。

    [结论] 噪声作业对柴油机厂工人心血管系统可能有一定程度的影响。

     

    Abstract:
    [Objective] To explore the abnormalities in ECG of the workers exposed to noise in a diesel engine factory.

    [Methods] The environment noise levels in different work places were detected and physical examination of 336 noise-exposed workers were performed in a Diesel engine factory. Their ECG abnormalities were also analyzed. Another 293 non noise-exposed workers in the same factory were selected as the control group.

    [Results] The abnormal rate of ECG in the exposed group were significantly higher than those in the control group (P < 0.01).ECG abnormalities are mainly manifested as sinus bradycardia, sinus arrhythmia, ST-T abnormality and fascicular block. The abnormal rates of ECG in the exposed group in every work-age group were higher than those of the control group. The abnormal rate of ECG was most obvious in the initial period, and not increased when work-age increased.

    [Conclusion] The exposure of noise might have certain impact on cardiovascular system.
