The influence of pulsed high-frequency electromagnetic fields emitted by digital mobile radio telephones on heart rate during sleep in healthy humans was investigated. Beside mean RR interval and total variability of RR intervals based on calculation of the standard deviation, heart rate variability was assessed in the frequency domain by spectral power analysis providing information about the balance between the two branches of the autonomic nervous system. For most parameters, significant differences between different sleep stages were found. In particular, slow-wave sleep was characterized by a low ratio of low- and high-frequency components, indicating a predominance of the parasympathetic over the sympathetic tone. In contrast, during REM sleep the autonomic balance was shifted in favor of the sympathetic activity. For all heart rate parameters, no significant effects were detected under exposure to the field compared to placebo condition. Thus, under the given experimental conditions, autonomic control of heart rate was not affected by weak-pulsed high-frequency electromagnetic fields.
研究了数字移动无线电话发出的脉冲高频电磁场对健康人睡眠期间心率的影响。除了基于标准差计算的平均RR间期和RR间期的总变异性外，还通过频谱功率分析在频域评估心率变异性，以提供有关自主神经系统两个分支之间平衡的信息。对于大多数参数，发现不同睡眠阶段之间存在显著差异。特别是，慢波睡眠的特征是低频和高频成分的比例较低，表明副交感神经占主导地位，交感神经活动较弱。相比之下，在快速眼动睡眠期间，自主神经平衡向有利于交感神经活动的方向转变。对于所有心率参数，与安慰剂条件相比，在暴露于该场的情况下未检测到显著影响。因此，在给定的实验条件下，弱脉冲高频电磁场不会影响心率的自主控制。
