58名(调查组)长期接触CO隧道工人心电图进行了分析,均为男性,年龄27～42岁,平均年龄33岁。接触工龄2～2.5年,日平均工作4～6小时。工种为凿岩工、爆破工、运输司机、混凝土工、管道工等。接触CO浓度范围10～700mg/m~3,平均为180mg/m~3。对照组系医院男卫生员30人,均为不接触各种有害气体,年龄27～39岁,平均年龄31岁。结果表明:调查组心电图异常检出率为46.9％,其中窦性心动过缓、窦性心律不齐、不完
Fifty-eight (Investigation Team) long-term exposure to CO tunnel workers ECG were analyzed, both men, aged 27 to 42 years, mean age 33 years. Exposure to working age 2 ~ 2. 5 years, the average daily work of 4 to 6 hours. Work for the drilling workers, blasting workers, transport drivers, concrete workers, plumbers and so on. Exposure to CO concentration range 10 ~ 700mg / m ~ 3, with an average of 180mg / m ~ 3. The control group of hospital male health workers 30 people, are not exposed to a variety of harmful gases, aged 27 to 39 years old, with an average age of 31 years. The results showed that: the detection rate of abnormal electrocardiogram in the investigation group was 46.9%, of which sinus bradycardia, sinus arrhythmia, incomplete
