Abstract

The technological advancement has led to the exponential use of wireless devices leading to the concern for the\nanalysis of their side effects on the human health. This paper presents the review of the researches conducted from time to\ntime, in order to study the impact of radiations from mobile phones, base transceiver station (BTS), Wi-Fi etc. on the\nelectrocardiogram (ECG), heart rate variability (HRV), blood pressure etc. The different parameters used to assess the HRV\nhave also been reviewed. The various biological effects of these radiations are also discussed in this paper.
