Effect of mobile phone radiofrequency electromagnetic fields on cardiovascular parameters in apparently healthy individuals.

この研究は、心臓の近くに置いた携帯電話心臓電気的なリズムに干渉する、あるいは血圧に影響を及ぼすかどうかを調べた。インフォームド・コンセントを取得した後、無作為に選択した見かけ上健康な男性ボランティア18人(21.44±0.53歳)について、携帯電話への急性ばく露の前後に血圧、脈拍、心電図を測定した。心電図パラメータとして、心拍変動(HR)、QRS時間(QRS)、PRインターバル(PR)、補正QTインターバル(QT)を取得した。その結果、携帯電話へのばく露の前後で、血圧および脈拍に有意差は認められなかった。心電図パラメータは通話の前後で変わらなかった。著者らは、これらの結果は、心臓の近くに置いた携帯電話からの電磁界への急性ばく露は、健康な個々人の心臓電気的活動または血圧干渉できないことを示唆している、と結論付けている。

研究目的(著者による)

The effects of exposure to the electromagnetic field from a mobile phone on the human ECG and blood pressure should be investigated.

詳細情報

A total of 18 randomly selected apparently healthy male volunteers participated in the study. It comprised 1 session during which the subject's ECG was measured in a resting state without a mobile phone (baseline), with a mobile phone in on-mode placed on the chest, with the same mobile phone being called 3 times and again with the same mobile phone still in on-mode placed on the chest after the calls. ECG measurements in each phase lasted 5 minutes. Before and after the ECG measurements, blood pressure was measured.

研究の主なアウトカム(著者による)

No significant differences were found in blood pressure or pulse rate between measurements before and after the exposure. Moreover, no significant differences were found in ECG parameters before, during or after calls compared to the baseline values.
The authors conclude that there are no indications for an effect of exposure to the electromagnetic field from a mobile phone on the human ECG or blood pressure.
