This investigation studied the effect of 50 Hz electric and magnetic fields on the human heart. The electrocardiograms of 27 transmission-line workers and 26 male volunteers were recorded with a Holter recorder both in and outside the fields. The measurements took from half an hour to a few hours. The electric field strength varied from 0.14 to 10.21 kV/m and the magnetic flux density from 1.02 to 15.43 microT. Analysis of the ECG recordings showed that extrasystoles or arrhythmias were as frequent outside the field as in the field. In some cases a small decrease in heart rate was observed after field exposure.
本研究调查了50赫兹电场和磁场对人体心脏的影响。使用动态心电图记录仪记录了27名输电线路工人和26名男性志愿者在电场内外的心电图。测量时间从半小时到数小时不等。电场强度在0.14至10.21 kV/m之间变化，磁通密度在1.02至15.43微特斯拉之间变化。对心电图记录的分析表明，早搏或心律失常在电场外和电场内出现的频率相同。在某些情况下，观察到暴露于电场后心率略有下降。
