结合棉纺厂的特点,本文作者试图通过对900例心电图的分析,探讨噪音与窦性心动过速的关系。将调查对象分为织布、纺纱以及外部和科室三部份(外部包括电动部、机修和基建等部门),每部份抽样300例进行分析比较。结果:(1)窦性心动过速者(以下简称“窦速”)以噪音高的织布车间(103-105分贝)和纺织车间(94-100分贝)较多。织布车间的单纯窦速发病者49例(占该组被调查人数的16.3％);纺纱车间的发病者41例(41:300,13.6％);外部及科室的发病者11例(11:300,3.6％)。(2)窦速的频率在
Combined with the characteristics of cotton mills, the author attempts to analyze the relationship between noise and sinus tachycardia by analyzing 900 cases of electrocardiogram. The survey object is divided into three parts: weaving, spinning and external and department (external including electric department, mechanics and infrastructure and other departments), each part of the sample for analysis and comparison of 300 cases. Results: (1) Sinus tachycardia (hereinafter referred to as “sinus speed”) with high noise weaving workshop (103-105 dB) and textile workshop (94-100 dB) more. In the weaving workshop, there were 49 cases (19.3%, 13.6%) of the patients with simple sinus speed in the group, 41 cases (41.6%) in the spinning workshop, 11 cases (11 : 300, 3.6%). (2) sinus speed in the frequency
