The increasing use of mobile phones in recent years has caused concerns about the effects of electromagnetic waves of mobile phonesonhuman biological processes.
This study was conducted in order to survey the effects of mobile electromagnetic waves on electro cardiogram parameters as heart rate, TP segment, PR interval, Time of QRS and T waves, and voltage of R wave.
In this quasi experimental study, 40 students, of Zahedan medical science University, 20 boys and 20 girls, who had referred to the laboratory of physiology were selected. At first a normal electro cardiogram in lead I was recorded for each of the subjects for 20 seconds. Then a mobile phone was placed near their body and while mobile was ringing and talking two other electrocardiograms were recording for 20 seconds. Electro cardiograms were recorded with power lab device and analyzed by chart 5 software. Finally an ANOVA was employed to analyze the data through the SPSS 17, followed by a Tukey test.
There was significant difference between heart rate during talking in comparison with heart rate during ringing and resting in both genders. There was a significant decrease of resting TP segment in comparison with TP segment during ringing and talking in males whereas in females TP segment indicated significant difference in all three conditions. There was a significant increase in T wave time in males during talking in comparison with resting and ringing; however there was no significant difference in that of females in any of the three stated conditions. This study revealed that there is not any significant difference in PR interval, Time of QRS wave and R wave voltage.
According to the results of this study, mobile phones can affect the heart rate, TP segment and time of T wave. Therefore, it seems that long term use can affect heart. Based on several reports on the effects of these waves on biological processes, precautionary measures should be taken about using mobile phones.
近年来手机使用的增加引发了人们对手机电磁波对人体生物过程影响的担忧。
进行本研究以调查手机电磁对心电图参数的影响，如心率、TP段、PR间期、QRS波和T波时间以及R波电压。
在这项准实验研究中，选择了40名扎黑丹医科大学的学生，其中20名男生和20名女生，他们被转介到生理实验室。首先，为每个受试者记录I导联的正常心电图20秒。然后将一部手机放在他们身体附近，在手机响铃和通话时再记录另外两份心电图各20秒。心电图用PowerLab设备记录，并用Chart 5软件进行分析。最后，通过SPSS 17使用方差分析来分析数据，随后进行Tukey检验。
在通话期间的心率与响铃和休息期间的心率相比，男女均存在显著差异。男性休息时的TP段与响铃和通话时的TP段相比显著降低，而女性在所有三种情况下TP段均显示出显著差异。男性在通话期间的T波时间与休息和响铃相比显著增加；然而，在所述三种情况中的任何一种情况下，女性的T波时间均无显著差异。本研究表明，PR间期、QRS波时间和R波电压没有任何显著差异。
根据本研究结果，手机会影响心率、TP段和T波时间。因此，长期使用似乎会影响心脏。基于关于这些波对生物过程影响的几份报告，应该对使用手机采取预防措施。
