The influence of extremely weak alternating magnetic fields (EW AMF) with amplitudes of < or = 2 microT on the heart rate variability in humans has been studied. The volunteers were placed in a large- volume square coils system (2x2x2 m), which provided the exposure of the whole body to extremely weak alternating magnetic fields homogeneous in amplitude. It was shown that the exposure of volunteers to different types of extremely weak alternating magnetic fields can both increase and decrease the magnitude of stress. In particular, the field tuned to the nuclear spins of hydrogen atoms (amplitude 1.6 microT, frequency 76 Hz) induces a decrease in the Baevsky's stress index, while the field tuned to the magnetic moments formed by the orbiting electrons in some atoms (amplitude 0.192 microT, frequency 3000 Hz) increases the stress index. The results obtained provide a possible explanation for the mechanism of adverse effects of some particular types of technogenic and natural extremely weak alternating magnetic fields on the human cardiovascular system.
研究了振幅≤2微特斯拉的极弱交变磁场(EW AMF)对人体心率变异性的影响。志愿者被安置在一个大体积方形线圈系统(2×2×2米)中,该系统可使全身暴露于振幅均匀的极弱交变磁场中。结果表明,志愿者暴露于不同类型的极弱交变磁场中,既可能增加也可能降低应激程度。特别是,调谐到氢原子核自旋的磁场(振幅1.6微特斯拉,频率76赫兹)会导致别列夫斯基应激指数降低,而调谐到某些原子中轨道电子形成的磁矩的磁场(振幅0.192微特斯拉,频率3000赫兹)则会增加应激指数。所得结果为某些特定类型人为和自然产生的极弱交变磁场对人体心血管系统产生不良影响的机制提供了一种可能的解释。
