摘　　要：目的探讨对讲机微波辐射对作业人员心电图影响。方法于2004年6—7月,选择某企业165名经常使用对讲机的男保安员(工龄为0.5～3.32a)为暴露组,待其使用对讲机后进行心电图检查,另选择该企业80名不使用对讲机的健康男职工(工龄为0.5～3.58a)作为对照组进行心电图检查。结果暴露组窦性心律不齐和窦性心动过缓的百分率、心电图总异常率均高于对照组(P<0.05,P<0.01),暴露组平均心率低于对照组(P<0.01),暴露组P-R间期及Q-T间期比对照组均有延长(P<0.05)。结论该调查中的对讲机使用者心图的改变可能与暴露于对讲机的微波辐射有关。Objective To explore the effects of microwave radiation from interphone on the electrocardiogram of occupational population. Methods 165 male security personnels （working age： 0.5-3.32 a） often exposed to microwave radiation from interphone and 80 male staffs （working age： 0.5-3.58 a） without exposure to microwave radiation in a same security guard company were selected for examination of electrocardiogram in June-July,2004. Results The prevalences of sinus arrhythmia,sinus bradycardia,and the total abnormal rate of electrocardiogram in exposure group were significantly higher than those in control group（P〈0.05,P〈0.01）,the average heart rate in exposure group was significantly lower than that in the control group （P〈0.01）. The P-R interval and Q-T interval in exposure group were significantly longer than those in control group（P〈0.05）. Conclusion Exposure to microwave radiation from interphone may affect the electrocardiogram of occupational population.
