Effects of Acute Exposure to WIFI Signals (2.45 GHz) on Heart Variability and Blood Pressure in Albinos Rabbit

"These results suggest for the first time, as far as we know, that exposure to WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system."

Highlights

• ECG and arterial pressure measurements were studied under acute exposures to WIFI.
• Acute exposure of rabbits to WIFI increased heart frequency and arterial blood pressure.
• WIFI affect catecholamines (dopamine, epinephrine) efficacy on cardiovascular system.
• Radiofrequency can act directly and/or indirectly on cardiovascular system.

Abstract

Electrocardiogram and arterial pressure measurements were studied under acute exposures to WIFI (2.45 GHz) during one hour in adult male rabbits. Antennas of WIFI were placed at 25 cm at the right side near the heart.



Acute exposure of rabbits to WIFI increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI 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, WIFI 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 WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system.

Excerpts

The animals were exposed to an access point (AP) from WIFI device (D-Link DWL-3200 AP with 802.11 g mode and WPA2 network protection) as previously described in Salah et al. (2013). WIFI integrated two omnidirectional antennas that were setup for internet broadcast via wireless at 2.45 GHz. The sham control rabbits were placed under the same condition without applying RF (0 Hz). Antennas of WIFI were placed at 25 cm at the right side near the heart (animal in dorsal decubitus).

Experimental design: The rabbits were divided into six groups and for each group six rabbits and treated by intravenous injection as follows:
Group 1. Normal healthy control.
Group 2. Normal healthy: rabbits were exposed to WIFI one hour (between 9 h and 13 h).
Group 3. Rabbits were intravenously injected once with epinephrine (0.50 ml/kg).
Group 4. Rabbits were exposed to WIFI one hour (between 9 h and 13 h) following once intravenous injection of epinephrine (0.50 ml/kg).
Group 5. Rabbits were intravenously injected once with dopamine (0.50 ml/kg).
Group 6. Rabbits were exposed to WIFI one hour (between 9 h and 13 h) following once intravenous injection (iv) of dopamine (0.50 ml/kg).

Our results show clearly that WIFI increased heart rate and arterial blood pressure probably via direct and/or indirect pathways. The direct effects of RF could be related to their action on Ca++ and Zn++ homeostasis especially on divalent mineral flux modulated by EMF as shown previously by Amara et al. (2007).

Our studies point that WIFI is not completely safe at home near the animal or human body because it employ harmful radio waves. But it is safer compared to cellphone that it is close to our brain during communications. WIFI signals are everywhere. If you switched off your WiFi at night, you are still exposed to the WIFI signals coming in from neighbors but we have a significant reduction of the bioeffects of WIFI with distance from the router. Future investigations will focus on the long term bioeffects of WIFI placed at an important distance from the animal or the human.

Conclusion: These results suggested that exposure to WIFI (2.45 GHz) affect HR variability leading to tachycardia and hypertension. The WIFI alter the physiological action of catecholamines on cardiovascular system perhaps via the disruption of the interaction between ligand-receptors in rabbit.
