本文观察了52例暴露于不同强度稳态噪声女工的卧至直立位ECG(心电图)。结果表明,高强度噪声接触者主要表现心脏交感神经兴奋性降低的植物神经功能失调倾向,而迷走神经功能没有明显改变。此外,在低于国家卫生标准的噪声强度下,未显示出对心脏植物神经功能改变。
In this paper, 52 cases of pregnant women exposed to steady-state noise of different levels to the upright position ECG (ECG). The results showed that high-intensity noise exposure mainly showed dysfunction of autonomic aortic sympathetic dysfunction while vagal function was not significantly changed. In addition, at lower than the national health standards of noise intensity, did not show changes in cardiac autonomic function.
