“…However, as in all experimental studies, only the immediate responses to exposure were observed. It did not allow for monitoring of the delayed effects related to long-term exposure [25,30] which is most prevalent in the occupational setting.…”

Objectives: The aim of the study was to assess the mechanism of cardiovascular impairments in workers exposed to UHF-VHF radio frequency electromagnetic fields (EMF). Materials and Methods: Heart rate variability (HRV) was analysed using 512 normal heart beats registered at rest. The analysis concerned time-domain (STD R-R) and frequencydomain (VLF, LF, HF) parameters of HRV. Fifty nine workers (group I) with low-level and 12 workers (group II) with highlevel exposure were examined. The mean age of the subjects was 47±9 years and 41±14 years, and mean exposure duration 19.1±8.8 years and 13±4 years, in groups I and II, respectively. The groups were divided according to: E max , E dose , E mean for frequencies UHF, VHF and UHF+VHF: The control group consisted of 42 non-exposed subjects, aged 49±8 years. Statistical analysis comprised one-way analysis of variance, covariance analysis and logistic regression models. Results: In the exposed groups, the heart rate was higher than in the control one. Standard deviation of R-R intervals (STD R-R) was found to be significantly (p = 0.0285) lower in group I (42.5±24.7 ms) compared to the control group (62.9±53.5 ms). The risk of lowered STD R-R was significantly increased (OR = 2.37, p = 0.023) in group II. Both exposed groups presented significantly higher VLF and LF values than the control group (p = 0.005 and p = 0.0025, respectively). The EMF-exposed groups were characterised by the dominance of the sympathetic system (LF/HF 1.3±0.35). Conclusions: The results indicate that exposure to radiofrequency EMF may affect the neurovegetative regulation.

“…The effects of cell phones on the cardiovascular system have been investigated by various researchers by examining parameters such as heart rate and blood pressure but the study results are controversial (13,14). To the best of our knowledge, the effects of exposure to EF on hemorheological parameters have not been studied before.…”

“…EM radiation has been shown to cause changes in living tissues such as altering the permeability of the blood-brain barrier, encephalogram and blood pressure, mostly through 'nonthermal' pathways [16]. Lower frequency EM fields appear to be more bioactive than higher frequency fields of the same rest characteristics [17].…”
