Effects of acute exposure to WIFI signals (2.45GHz) on heart variability and blood pressure in Albinos rabbit.

[In questo recente articolo, viene dimostrato un chiaro effetto delle frequenze emesse dai sistemi Wi-Fi  sulla variabilità del ritmo cardiaco e della pressione sanguigna, in animali da esperimento esposti nell’ambito di una procedura randomizzata.
Questo dato conferma i noti effetti delle radiofrequenze e microonde sul sistema cardiovascolare dell’uomo.
In particolare M. Havas, in sperimentazioni sull’uomo, ha messo in evidenza come proprio la frequenza a 2.4 GHz tipica del Wi-Fi (e del forno a microonde) sia in grado di alterare il sistema nervoso autonomo che governa l’attività cardiaca.
I bambini che frequentano le scuole elementari e medie, ormai dotate di sistemi di trasmissione dati tramite Wi-Fi, rischiano di avere seriamente compromessa l’attività di una pompa vitale come quella cardiaca.
Pertanto si rende necessario applicare con massima urgenza il principio di precauzione, eliminando questi pericolosi sistemi di trasmissione in favore di sistemi cablati, come raccomandano da tempo sia il Parlamento Europeo che il Consiglio d’Europa…prima che sia troppo tardi.]

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 (2.45GHz) during one hour in adult male rabbits. Antennas of WIFI were placed at 25cm 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 (0.50ml/kg) and epinephrine (0.50ml/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.
