Heart rate variability monitoring due to 50 Hz electromagnetic field exposure and statistical processing

Abstract

This study investigates the influence of the 50 Hz electromagnetic exposure on heart rate variability (HRV). Thus, we recorded and preceded the ECG signals for 44 volunteers both in high and normal field exposure. The acquisition system and the QRS detection algorithm were developed by the authors with the view to be used in this study. Spectral measurements of the HRV revealed a significant increase (Student's t-test: P t =0.001; Mann-Whitney U-test P U =0.001; average difference D=16.857) in the power of the HF components and significant reduction in the power of the low-frequency (Student's t-test: P t =0.003; Mann-Whitney U-test P U =0.003; average difference D=-14.906) on volunteers exposed compared with unexposed one conditions.

“…HRV is also a method used to evaluate the stress [4] and other stimulus. There are some studies referring to HRV analysis in the case an electromagnetic field exposure [5], [6], [7].…”
