Abstract

Objective: In this study, the effects of radiation emitted from mobile phone (MP) on heart rate variability (HRV) which is accepted a non-invasiveindicator of autonomic nervous system (ANS) were investigated with considering the deficiency of previous studies.Methods: A randomized controlled study has been designed and utilized with 30 young and healthy volunteers. During the experiment that hadthree periods, the electrocardiogram (ECG) and respiration signals were recorded and MP was attached to subjects right ear with a bone. Tensubjects selected randomly were exposed to high -level radiation during the second period (Experimental Group 1). Ten of others were exposedduring the third period with maximum level radiation (Experimental Group 2). Ten records were also made while MP was closed as a control.Short -term HRV parameters were obtained and repeated measures ANOVA and suitable post-hoc tests applied to the results.Results: According to the results of the repeated measures ANOVA; there were no significant main effects of groups. However, there were somesignificant differences in measuring time periods and groups*period interactions. The post-hoc tests showed that mean R to R interval and HFpower are significantly changed by maximum radiation emitted from MP.Conclusion: Due to the radiation emitted from MPs at maximum power, some changes may occur in HRV parameters that are associated withincreased parasympathetic activity. But, the level of these changes is similar to daily activities as excitement, and stand up. (Anadolu Kardiyol Derg 2012; 12: 406-12)

Özet

Amaç: Bu çalışmanın amacı; cep telefonlarından (CT) yayılan radyasyonun, otonom sinir sisteminin (OSS) girişimsiz bir göstergesi olarak kabuledilen, kalp hızı değişkenliği (KHD) parametreleri üzerindeki etkilerini, bu alanda daha önce yapılan çalışmalardaki eksiklikleri dikkate alarakincelemektir.Yöntemler: Bu amaçla, 30 genç ve sağlıklı deneğin katıldığı randomize kontrollü bir çalışma gerçekleştirilmiştir. Üç periyot şeklinde düzenlenendeney sırasında, CT deneklerin sağ kulağına bir bone vasıtası ile tutturulmuş durumda iken, elektrokardiyogram (EKG) ve solunum sinyallerikaydedilmiştir. Denekler içerisinden rastgele olarak seçilen 10 tanesi; üç deney periyodunun ikincisinde (Deney Grubu 1), 10 tanesi üçüncüsünde (Deney Grubu 2) CTden yayılan maksimum güçlü radyasyona maruz bırakılmıştır. Kontrol grubunda CT kapalı tutulmuştur. Hesaplanan kısadönem KHD parametrelerine, tekrarlı varyans analizi ve çoklu karşılaştırma testleri uygulanmıştır.Bulgular: Tekrarlı varyans analizi sonucuna göre; gruplar arası değişkenliğin önemli olmadığı fakat deney periyotları arasında bazı parametrelerde anlamlı farklar olduğu ve bu farkların gruplara göre değişik periyotlarda yer aldığı görülmüştür. Çoklu karşılaştırma testleri sonucunda;CTden yayılan maksimum güçlü radyasyon sebebi ile kalp atım periyotları ve HF gücünde anlamlı farklar bulunmuştur.Sonuç: CTden yayılan maksimum güçlü radyasyon, genç ve sağlıklı bireylerin KHDlerinde parasempatik otonom aktivite artışından kaynaklanandeğişimlere sebep olabilir. Fakat bu değişimler günlük aktiviteler (heyecanlanma, sıkılma, ayağa kalkma vb.) sırasında görülebilecek KHD deği- şimleri ile benzer seviyededir. (Anadolu Kardiyol Derg 2012; 12: 406-12)
