目的探讨轨道车驾驶作业对轨道车司机心血管系统的影响。方法选择241名轨道车司机和37名新加入人员进行血压测量和常规心电图检查。结果新加入人员心血管系统功能改变低于轨道车司机组,其中高血压患病率差异有统计学意义(P<0.01);随着工龄增加,轨道车司机心血管系统功能异常检出率增加,其中高血压随着工龄增加,差异有统计学意义(P<0.01);新加入人员心电图异常检出率低于轨道车司机组,差异有统计学意义(P<0.05);同时ST-T段改变发生率也低于轨道车司机组,差异有统计学意义(P<0.05)。结论轨道车驾驶作业对驾驶人员的心血管系统功能有一定程度的影响,应加强对轨道车司机心血管系统的职业健康监护,以保证行车安全。
Objective To explore the influence of railcar driving on the cardiovascular system of railcar drivers. Methods 241 railcar drivers and 37 new recruits were selected for blood pressure measurement and routine electrocardiogram examination. Results The changes of cardiovascular system function of new recruits were lower than that of the rail car driver group, and the prevalence of hypertension was significantly different (P <0.01). With the increase of seniority, the detection rate of abnormal cardiovascular system function of rail car drivers was increased (P <0.01). The detection rate of abnormal electrocardiogram (ECG) of new recruits was lower than that of the rail car driver (P <0.05), while ST-T The incidence of segment change was also lower than that of the rail car driver group, the difference was statistically significant (P <0.05). Conclusion The operation of railcar has a certain degree of influence on the cardiovascular system function of drivers. Occupational health monitoring of the cardiovascular system of railcar drivers should be strengthened in order to ensure traffic safety.
