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/cm2, but did not show up obviously in ones exposed to the field of 0.005~0.010mW/cm2.
