ABSTRACT:
Background: A large number of publications have
appeared in medical and scientific literature which show the hazardous effects
of the mobile phone due to its radiofrequencies on reproductive system,
autonomic nervous and immune system as well as cardiovascular system. However,
so far the biological effect of the radiofrequency emitted from the mobile
phone was not clear. Aim: To assess the effect of mobile phone on electrical
cardiac activity by analysing the heart rate, QT interval, corrected QT
Interval and QT dispersions while the mobile phone is to the proximity of
heart. Settings and Design: This prospective, non-randomized study was carried
out at private tertiary care hospital, for the period of 24 months. Methods and
Material: One hundred healthy human volunteers were recruited in the study
based on inclusion and exclusion
criteria. The heart rate and 12-lead electrocardiogram (ECG) were recorded in
all the participants (supine position) in 3 situations: without mobile phone,
mobile phone switched on (not ringing), and mobile phone ringing. We performed
statistical analysis of variance (p > 0.05). Conclusions: We conclude that the mobile phone
positioned to the proximity of the heart has no effect on the heart rate or
cardiac electrical activity.
