摘要
本文观察74例超短波作业人员的卧-坐位ECG.结果表明,长期接触0.7～0.8mW/cm^2超短波辐射的工作者可呈心迷走神经张力占优势,而交感神经兴奋则降低的植物神经功能紊乱的表现.0.005～0.010mW/cm^2强度的超短波辐射对心脏植物神经的作用不明显.
The ECG, of 74 occupational workers in lying or sitting position who had been exposed to ultrashort waves was performed. The results showed that the dysfunction of cardiovascular autonomic nerve characterized by prevailing vagotonia and depressing sympathesis, appeared in these long exposed to ultrashort wave field of 0.7～0.8mW/cm^2, but did not show up obviously in ones exposed to the field of 0.005～0.010mW/cm^2.
