目的了解煤矿井下作业工人心血管系统受损情况。方法对部分煤矿井下工人(观察组)398人,以及非煤矿井下工人(对照组)415人进行心电图检查情况比较。结果观察组心电图异常检出率为34.17%,高于对照组的12.77%,其中以窦性心动过缓和左心室高电压较为明显,且差异均有显著性(P<0.05)。在不同工龄观察组心电图异常检出率均高于对照组,差异有显著性(P<0.05);但观察组经趋势卡方检验,各组人员的工龄心电图异常检出无关联(P>0.05)。结论煤尘和长期精神高度紧张、恐惧、劳动强度等因素,容易发生心血管系统的疾病造成心电图改变,应引起有关部门高度重视。
Objective To understand the damage of cardiovascular system in coal miners. Methods A total of 398 people working in some coal miners (observation group) and 415 people in non-coal mine workers (control group) were compared electrocardiographically. Results The detection rate of electrocardiogram abnormality in observation group was 34.17%, which was higher than that in control group (12.77%). The sinus bradycardia and left ventricular high voltage were obvious and the difference was significant (P <0.05). The detection rate of electrocardiogram abnormalities in observation group at different ages was higher than that in control group (P <0.05), but there was no correlation between working age and ECG abnormalities in observation group by chi-square test (P> 0.05 ). Conclusion Coal dust and long-term mental stress, fear, labor intensity and other factors, prone to cardiovascular diseases caused by ECG changes should be caused by the relevant departments attach great importance.
