In total, 44 subjects took part in the study. However, 12 were excluded due to movement artifacts in the electrocardiogram or imperfect electrode contacts. Hence, 32 subjects (n=14 exposed, n=18 control) were considered for the analysis.
Remark EMF-Portal: No details given for exposure procedure or parameters, e.g. unclear if subjects were only exposed to a magnetic field or additionally to an electric field.

In exposed subjects, the variation of the amplitude of the QRS complex and the mean heart rate were significantly decreased compared to the non-exposed control subjects while the mean RR interval was significantly increased. Additionally, the power spectral density of the heart rate variability was significantly decreased in the low frequency band and significantly increased in the high frequency band in exposed subjects compared to control subjects.
The authors conclude that 50 Hz magnetic field exposure could influence the heart rate variability in humans.
