The aim of this study was to test whether the electromagnetic field emitted by standard GSM mobile phones results in changes in heart rate and heart rate variability in humans.
Thirty-five healthy male and female subjects (mean age: 22 years) participated. In each experimental session, 150 individual heart beats were analysed. Photoplethysmography measurements were taken 0, 30, 50, and 70 minutes after exposure and compared to ECG analyses.
|ばく露時間||continuous for 10 min|
|Pulse width||0.58 ms|
|Repetition frequency||217 Hz|
|ばく露装置の詳細||RF exposure was tested in a randomised one-shot repeated measures design. Both groups (RF and sham) were first examined in a supine resting and then in a standing position each lasting for 5 min.|
|Sham exposure||A sham exposure was conducted.|
|Additional information||The sham group held the phone in the same position that was connected to a dummy load to avoid RF exposure [Parazzini et al., 2005].|
There was no significant difference in the values of heart rate and heart rate variability between the radio frequency exposure and the sham exposure groups neither using ECG nor using photoplethysmography. The radio frequency fields emitted by cellular phones did not cause observable effects on the regulation of heart rate in healthy, young adults.
