Effect of mobile phone radiofrequency electromagnetic fields on cardiovascular parameters in apparently healthy individuals. med./bio.

Published in: Niger J Physiol Sci 2014; 29 (2): 137-140

Aim of study (acc. to author)

The effects of exposure to the electromagnetic field from a mobile phone on the human ECG and blood pressure should be investigated.

Background/further details

A total of 18 randomly selected apparently healthy male volunteers participated in the study. It comprised 1 session during which the subject's ECG was measured in a resting state without a mobile phone (baseline), with a mobile phone in on-mode placed on the chest, with the same mobile phone being called 3 times and again with the same mobile phone still in on-mode placed on the chest after the calls. ECG measurements in each phase lasted 5 minutes. Before and after the ECG measurements, blood pressure was measured.

Main outcome of study (acc. to author)

No significant differences were found in blood pressure or pulse rate between measurements before and after the exposure. Moreover, no significant differences were found in ECG parameters before, during or after calls compared to the baseline values.
The authors conclude that there are no indications for an effect of exposure to the electromagnetic field from a mobile phone on the human ECG or blood pressure.
