Acute Effect of Mobile Phone on Cardiac Electrical Activity in Healthy Volunteers med./bio.

Published in: Int J Clin Med 2014; 5 (5): 167-170

Aim of study (acc. to author)

To investigate whether exposure to the radiofrequency field of a mobile phone influences cardiac parameters in an electrocardiogram (ECG) in healthy volunteers.

Background/further details

In total, 100 volunteers were examined under three conditions: First, ECG was recorded without a mobile phone (baseline), then mobile phone was in standby mode and finally mobile phone was "ringing" (incoming call, but absolutely soundless and without vibration).



Exposure Parameters
Exposure 1: 900–1,800 MHz
Exposure duration: not given

  • during exposure

Main outcome of study (acc. to author)

No significant differences were observed when mobile phone was in standby mode or during an incoming call in comparison to the baseline.
The authors conclude that the mobile phone has no effect on cardiac parameters in healthy volunteers.
