Brain frequency magnetic fields alter cardiac autonomic control mechanisms.
Sastre A, Graham C, Cook MR. Sastre A, et al. Clin Neurophysiol. 2000 Nov;111(11):1942-8. doi: 10.1016/s1388-2457(00)00438-7. Clin Neurophysiol. 2000. PMID: 11068227
CONCLUSIONS: Magnetic field exposure in the EEG/MEG beta(1) frequency range alters HRV via a CNS effect. Phase-resetting experiments rule out a direct effect on the cardiac pacemaker. Biophysical calculations of the intensity of the electric fields induced in brain …
