View Original AbstractMobile phones placed directly on the chest showed no immediate heart effects in healthy adults during 30-minute exposure periods.
Plain English Summary
Turkish researchers tested whether mobile phones placed directly on the chest affect heart function in 24 healthy volunteers. They measured heart rate, blood pressure, and electrical activity of the heart when phones were off, on, and ringing. The study found no significant changes in any heart measurements, suggesting that mobile phones positioned near the heart do not immediately disrupt cardiac function in healthy adults.
Study Details
The aim of this study was to evaluate the effect of mobile phone (MP) on cardiac electrical activity by examining the heart rate variability (HRV), QT, P dispersions and blood pressure (BP) while the MP is located on the precordium.
A total of 24 healthy volunteers were included in this prospective study. In the first step; 12-lead...
There were no statistically significant differences between the groups in the BP, heart rate, P-wave...
We conclude that MP has no effect on hemodynamic (heart rate, blood pressure) and cardiac electrical activity (P-wave and QT dispersions) parameters when it is positioned on the chest in immediate proximity to the heart, and it does not cause cardiac autonomic dysfunction examined by HRV analysis in healthy adult subjects.
