 Effects of acute exposure to WIFI signals (2.45 GHz) on heart variability and blood pressure in Albinos rabbit. Linda Saili. Amel Hanini, Chiraz Smirani, Ines Azzouz, Amina Azzouz, Mohsen Sakly, Hafedh Abdelmelek, Zihad Bouslam. Environmental Toxicology and Pharmacology. 40(2):600-605. September 2015, 

  • 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."


  • 10 of the subjects (40 percent) displayed increased heart rate, arrhythmias(irregular heartbeats, a.k.a. heart palpitations). 

  • Four subjects experienced overt tachycardia, or intense and prolonged heart racing, after a second or two of exposure, with one subject’s heart almost tripling its rate. 

  • Strong increases in sympathetic nervous activity and decreases in parasympathetic activity from exposures.

  • Provocation studies presented in this article demonstrate that the response to electrosmog is physiologic and not psychosomatic.  Those who experience prolonged and severe EHS may develop psychologic problems as a consequence of their inability to work, their limited ability to travel in our highly technologic environment, and the social stigma that their symptoms are imagined rather than real.

  • MDA and NOx levels were increased significantly in liver, lung, testis and heart tissues of the exposed group compared to sham and control groups .(p < 0.05).

  • Results of our study showed that pulse-modulated RF radiation causes oxidative injury in liver, lung, testis and heart tissues mediated by lipid peroxidation, increased level of NOx and suppression of antioxidant defense mechanism.

  • Double blind, sham-controlled study documented an increased heart rate, altered HRV and changes in the sympathetic and parasympathetic control of the Autonomic Nervous System.

  • "Our results demonstrate that the radiation from a 2.4-GHz cordless phone affects the ANS and may put some individuals with preexisting heart conditions at risk when exposed to electromagnetic frequencies to which they are sensitive."
