Low pulsed microwave radiation induced temporary high fluctuations in the power spectra of heart rate variability signals in cats, specifically in the thermoregulatory control activity band.
Should not alter clinical practice; hypothesis-generating for microwave effects on autonomic HRV in mammals.
The main objective of this work is to study the effect of low pulsed microwaves on heart rate variability signals derived from electrocardiogram signals( ) of ten cats. The cats were irradiated with rectangular pulsed microwaves at . , peak, . us wide and repetition rate applied to their brains through horns and wave guides for min followed by a min recovery period after exposure. The results clearly indicate that the pulsed microwaves radiation induced high fluctuations in power spectra of heart rate variability signal( R ) specially in the band of s to s ( . to . ) which is related to the thermoregulatory control activity, examining the power spectra of R of recovery period (after min microwave exposure) shows that change of power spectra of R signals during microwave exposure is not permanent.

Ahmed Kamal (2007) studied this question. Low pulsed microwaves vs. Baseline and recovery period was evaluated on Power spectra of heart rate variability signals. Low pulsed microwave radiation induced temporary high fluctuations in the power spectra of heart rate variability signals in cats, specifically in the thermoregulatory control activity band.
