This investigation studied the effects of 50 Hz electric and magnetic fields on the pulse rate of the human heart. The ECG (electrocardiograms) of 41 male volunteers were recorded with a Holter recorder. Twenty-six subjects were measured in and outside real fields, and 15 subjects were measured in and outside "sham" fields. The blood pressure and EEG (electroencephalogram) were also measured, but this article presents only the results of ECG recordings. The measurements took 3 h. The subjects were first sitting for 1 h outside the fields, then 1 h in the real or "sham" fields, and then, again, 1 h outside the fields. The electric field strength varied from 3.5 to 4.3 kV/m and the magnetic flux density from 1.4 to 6.6 microT. An analysis of the ECG recordings showed that the subjects' pulse rates were the same in and outside the fields. No response occurred when the subjects were exposed to real or "sham" fields.
本研究调查了50赫兹电场和磁场对人体心率的影响。用动态心电图记录仪记录了41名男性志愿者的心电图（ECG）。26名受试者在真实场内外进行了测量，15名受试者在“假”场内外进行了测量。还测量了血压和脑电图（EEG），但本文仅呈现心电图记录的结果。测量耗时3小时。受试者首先在场地外坐1小时，然后在真实或“假”场地内坐1小时，然后再在场地外坐1小时。电场强度在3.5至4.3 kV/m之间变化，磁通密度在1.4至6.6微特斯拉之间变化。对心电图记录的分析表明，受试者在场内和场外的脉搏率相同。受试者暴露于真实或“假”场时未出现反应。
