Title Neurovegetative disturbances in workers exposed to 50 Hz electromagnetic fields
Bibliographic information 1st quarter 2006, Vol.19, No.1, p.53-60. 37 ref.
Abstract This study was undertaken to assess autonomic function in workers occupationally exposed to 50Hz electromagnetic fields (EMFs) by analyzing the heart rate variability. The study group comprised 63 workers of switchyard substations, aged 22-67 years and a control group of 42 workers with no EMF exposure. To assess the neurovegetative regulation of the cardiac function, heart rate variability (HRV) was analysed based on 512 normal heart beats recorded at rest. The relative risk of decreased HRV, calculated with use of a logistic regression model, was significantly higher in the exposed group than in controls (odds ratio 2.8). It is concluded that occupational exposure to 50Hz EMF could influence the neurovegetative regulation of the cardiovascular system.
