Electrocardiogram and arterial pressure measurements were studied under acute exposures to Wi-Fi (2.45 GHz) during one hour in adult male rabbits. Antennas of Wi-Fi were placed at 25 cm at the right side near the heart.
Acute exposure of rabbits to Wi-Fi increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that Wi-Fi induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50 ml/kg) and epinephrine (0.50 ml/kg) under acute exposure to RF we found that, Wi-Fi alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control.
These results suggest for the first time, as far as we know, that exposure to Wi-Fi affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system.
