Extract from the introduction: Several studies have shown that magnetic field exposure can affect heart rate (HR) and heart rate variability (HRV). In this pilot study, the authors studied HRV in a group of seven male train engine drivers, occupationally exposed to an intense magnetic field over one working day.

From the discussion: As this is a pilot study, the low number of participants is a major limitation. We have therefore not included a statistical analysis of the data in view of the low number of participants. However, the findings in the study indicate that it would be of interest to perform an HRV study with a larger number of participants who have a high occupational exposure to extremely low‐frequency magnetic fields.
