Abstract
Environmental epidemiologic studies have shown that elderly
people are susceptible to particulate air pollution. The
decreases in heart rate variability are important indices of
health effect caused by particulate matter. The objective
of this study was to investigate the effects of submicron
particle (PM1), PM1-2.5, and coarse particle (PM2.5-10) on
heart rate variability parameters in the elderly. Results of
our study indicated that short-term and medium-term PM
exposures were associated with the reduction of heart rate
variability in the elderly, with stronger effects found for
coarse particles in comparison with particles of other size
ranges.
