[目的]了解龙岩市某煤矿工人健康的危害情况。[方法]2007~2008年对龙岩市某煤矿井下作业工人142名进行心电图检查,并选择不接触有害因素的145名进行对照。[结果]心电图异常检出率,接触组为59.16%,对照组为34.48%(P<0.01)。其中,窦性心动过缓、左室高电压检出率,接触组分别为25.35%、21.83%,对照组分别为8.97%、8.28%(P<0.01)。接触组心电图异常检出常率,<30岁、30~39岁、≥40岁的分别为71.93%、67.86%、41.38%(P<0.05);工龄<5年、5~14年、≥15年的分别为57.45%、74.07%、41.46%(P<0.01)。[结论]长时间在井下作业可造成心电图的异常改变,年龄大、工龄长者异常改变尤为严重。
[Objective] To understand the health hazards of a coal mine worker in Longyan City. [Methods] From 2007 to 2008, 142 mine workers in a coal mine in Longyan City were examined by electrocardiogram, and 145 non-hazardous factors were selected for comparison. [Results] The detection rate of ECG abnormality was 59.16% in the contact group and 34.48% in the control group (P <0.01). Among them, sinus bradycardia, the detection rate of left ventricular high voltage, contact group were 25.35%, 21.83%, respectively, the control group were 8.97%, 8.28% (P <0.01). The detection rate of electrocardiogram anomaly in the contact group was 71.93%, 67.86% and 41.38% respectively (P <0.05), <30 years old, 30-39 years old, and 40 years old; Year were 57.45%, 74.07%, 41.46% (P <0.01). [Conclusion] The long time downhole operation can cause the abnormal change of ECG.
