Abstract

Recently peoples are concerned with safety of electromagnetic waves (EMW) emitted from mobile phone (MP) because neurological, degenerative, and heart diseases have been reported to be related with the use of MP. So, it is planned to study the effect of EMW emitted from MP on QT interval variables of electrocardiogram (ECG). Study was carried out in 15 healthy male subjects in the age group of 18–40 years. They were divided into two groups, i.e., MP nonuser group and MP user group. ECG was recorded in lead II for 5 min before and after listening to MP (1800 MHz frequency, band GSM type, model Panasonic GD75) which was held near to ear for a period of 30 min in on position on polyrite D system. On observing the acute effect of EMW emitted from MP, in MP non user group, R-R interval (P <0.001), QTc (p<0.05), P wave duration (p<0.001) and RPP were reduced (p<0.001), whereas R-R interval was reduced (p<o.oo1) and RPP was raised (p <0.001) in MP user group.

When subjects of nonuser group were compared with the subjects of user group in resting basal conditions, i.e., before exposing them to the MP, R-R interval (p < 0.05) was found to be increased, P-R interval was decreased (p<0.05) with non significant alteration in QRS, QTc, P wave, R wave, T wave duration and RPP in user group.

When nonuser group was compared with user group after exposure to electromagnetic waves, (acute on chronic effect), R-R interval and RPP were increased (p<0.001) without any effect on other parameters in user group. So, it is concluded that EMW emitted from MP may affects the ECG variables.
