Key result
Short-term mobile phone exposure fails to alter HRV parameters compared to baseline.
Why the study?
Does short-time exposure to electromagnetic fields emitted by mobile phones affect cardiac autonomic modulation in healthy young subjects?
Does short-time exposure to electromagnetic fields emitted by mobile phones affect cardiac autonomic modulation in healthy young subjects?
Short-time exposure to electromagnetic fields emitted by mobile phones does not affect cardiac autonomic modulation in healthy subjects.
Short-time mobile phone EMF exposure leaves HRV unchanged in healthy subjects; leaves open effects in patients or with chronic exposure.
BACKGROUND: It has long been speculated that mobile phones may interact with the cardiac devices and thereby cardiovascular system may be a potential target for the electromagnetic fields emitted by the mobile phones. Therefore, the present study was designed to test possible effects of radiofrequency waves emitted by digital mobile phones on cardiac autonomic modulation by short-time heart rate variability (HRV) analysis. METHODS AND RESULTS: A total of 20 healthy young subjects were included to the study. All participants were rested in supine position at least for 15 minutes on a comfortable bed, and then time and frequency domain HRV parameters were recorded at baseline in supine position for 5 minutes. After completion of baseline records, by using a mobile GSM (Global System for Mobile Communication) phone, HRV parameters were recorded at turned off mode, at turned on mode, and at calling mode over 5 minutes periods for each stage. CONCLUSION: Neither time nor frequency domain HRV parameters altered significantly during off mode compare to their baseline values. Also, neither time nor frequency domain HRV parameters altered significantly during turned on and calling mode compared to their baseline values. Short-time exposure to electromagnetic fields emitted by mobile phone does not affect cardiac autonomic modulation in healthy subjects.

Barutçu et al. (2011) studied Healthy (n=20). Mobile GSM phone exposure vs. Baseline was evaluated on Time and frequency domain heart rate variability (HRV) parameters. Short-time exposure to electromagnetic fields emitted by mobile phones did not significantly alter time or frequency domain heart rate variability parameters compared to baseline.
