Influence of Geopathic Stress Zone on Heart Rate variability Parameters

Background and Aim: Geopathic stress (GS)is the effect of detrimental earth radiation and electro-magnetic radiation on the health of human body. The aim of this study is to evaluate the effect of the geopathic stress on heart rate variability(HRV) parameters in healthy human subjects. Methods: The time and frequency  domain HRV analyses were performed to assess the changes in sympathovagal  balance in group of 60 healthy volunteers with normal electrocardiogram(ECG).Sixty volunteers we-re selected for the study with  no history of illness(40 healthy men volunteers, 20 healthy women vo-lunteers). By using the apparatus Rayocomp PS-10(German, Rayonex), Geopathic stress zone were measured. The time and frequency domain HRV analyses were performed befor and after 60 minutes stay of volunteers in Geopathic stress zone.  Results: During 60 minutes stay on the GS zone, the time domain parameters such as standard  deviation(SD, ms) of all normal sinus RR intervals were significantly decreased. Then frequency domain parameters such as very low frequency (VLF, ms2), low frequency (LF, ms), and the LF/HF ratio were significantly increased. Conclusion: The study indicated  that the stay of healthy human in the GS zone may influence heart rate variability and change the sympathovagal balance.
