The main objective of this double-blind 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. As we know already that our hearts and brains are bioelectrical systems which are regulated by internal bioelectrical signals.Environmental exposures to artificial EMFs can interact with fundamental biological processes in the human body. The increasing extensive use of cellular phones has generated public concern about exposure to the microwave radiation associated with these phones. The probable biological effects due to the use of the mobile phones can be regarded as a result of energy absorbed by the heart that may also damage the brain and nervous tissues. The conveniences and satisfaction derived in the use of GSM mobile phone are being threatened by assertions of adverse effects on human health by radiation coming from this device. This radiation belongs to the type called non-ionizing radiation the health hazard of which remains debatable. It is been also said that “When a GSM phone transmits, it immediately goes to the peak power, and then the power control circuitry ratchets down the power to an acceptable level. Also, CDMA phones operate at a fraction of their maximum outputs, emitting about 28 times less radiation than GSM phones”, ultimately making a GSM phone more harmful than that of CDMA.
