Heart Rate Variability Analysis in Workers Exposed to Methyl Bromide as a Quarantine Treatment.


ABSTRACT:

Objective

To determine whether methyl bromide (MB) fumigation work for plants imported in Korea affects workers' health by assessing heart rate variability (HRV).

Methods

We measured HRV indices (TP, VLF, LF, HF, HR, SDNN, pNN50 and HRV-index) and urinary bromide ion (Br-) in 62 fumigators (study group) and 34 inspectors (the control group) before and after fumigation work. In addition, the relationship between Br- concentration and HRV indices was analysed.

Results

The fumigators' post-work HRV indices and Br- level were changed compared with their pre-work values (P?ConclusionsFumigators with high Br- concentrations and low post-work HRV indices following MB fumigation work experienced adverse effects on their autonomic nervous systems.
