Abstract

Background: The electromagnetic radiations emitted by cellular telephones may influence the autonomic tone which modifies the functioning of the circulatory system.

Aim and Objectives: To estimate the effect of using mobile phones on heart rate variability (HRV) in first year medical students.

Method: ECG and HRV parameters are recorded in three periods, - when the subject is at rest without mobile phone (Period-I), with mobile phone kept on the left chest (Period-II) and when responding to a call by keeping the mobile over his right ear (Period-III) on 100 healthy subjects aged between 18 and 21 years of either sex.
Results:When the mobile was kept on chest or while attending a call,a decrease in high frequency (HF) in normalized units and increase in low frequency (LF) in normalized units and increase in the ratio of LF to HF (LF/HF) was observed in the frequency domain measures. Decrease in RR intervals, RMSSD and NN50 was observed in the time domain measures .

Conclusion: The participants showed a higher sympathetic tone and a lower parasympathetic tone while attending a call. The study proved the intense effects of handset radiofrequency radiations on autonomic balance in healthy subjects.
