铆接噪声对作业人员心电图影响初探

First discussion for effect of operator-workers electrocardiogram(ECG)for riveting noise

目的：通过对航空铆接噪声作业人员252人进行心电图描记，从而分析噪声强度、性质、类型与接触噪声工人心律失常的关系进行研究。方法：对噪声组选用常规九个导联诊断标准。结果：显示航空铆接噪声属高强度，高频率段为主的噪声（F=3．04P<0．05），从心电图异常改变，以心动过缓、心律不齐和心动过速为多见，特别是心律不齐占22．6％明显高于对照组（P<0．01）。结论：提示生产性噪声对心血管系统亦有较明显损害。

OBJECTIVE: For 252 aerospace rivet-operator noise workers,to research the relations between analysis noise pressure level nature type and exposure rivet-operator noise workers base on recording electrocardiogram(ECG). METHODS: Using routine nine lead diagnosis standard for noise group. RESULTS: Aerospace rivet-operator noise is noise of high pressure level and high frequency. (F=3. 05 P<0. 05 )Most of electrocardiogram(ECG)abnormal change is bradycardia arrhythmia and tachycardia. This arrhythmia have 22. 6% at special clear high compare dgroup(p<0.01). CONCLUSION: The results showed industry production noise to cardiovascularsys have showed injured.
