  • Title: Heart rate variability and physiological arousal in men exposed to 60 Hz magnetic fields.
    Author: Graham C, Sastre A, Cook MR, Kavet R.
    Journal: Bioelectromagnetics; 2000 Sep; 21(6):480-2. PubMed ID: 10972952.
    Abstract:
    In previous research, intermittent exposure to sinusoidal 60 Hz magnetic fields at a resultant flux density of 28.3 microT was found to alter heart rate variability (HRV) in men during night sleep. When the 24 men in the present study were exposed under similar conditions, HRV was not altered. The previous studies included the hourly collection of blood samples via an indwelling venous catheter, while the present study did not. This may account for the observed differences in results. Further research is needed to determine if field exposure interacts with physiological arousal mechanisms to alter autonomic nervous system control over cardiac rhythms.
