本文比较89例200～300mW/m~2脉冲超高频或脉冲微波作业人员卧或卧一立位ECG中反映心脏植物神经功能的R-R间期变化。结果表明,脉冲超高频作业者仅有吸呼差一项指标量值增大。微波作业人员的各项R-R间期变化与对照组相比均无显著差异。作者认为,我国现行的作业场所超高频和微波卫生标准是合理并可行的。
In this paper, the R-R interval changes of cardiac autonomic nerve function in 89 patients with 200 ~ 300mW / m ~ 2 pulsed UHF or pulsed microwave were compared. The results show that the pulsed UHF operator only has a larger value of one index. There was no significant difference in the R-R interval between the microwave workers and the control group. The author believes that China’s current workplace UHF and microwave health standards is reasonable and feasible.
