Effects of Particle Size Fractions on Reducing Heart Rate Variability in Cardiac and Hypertensive Patients

Abstract
It is still unknown whether the associations between particulate matter (PM) and heart rate variability (HRV) differ by particle sizes with aerodynamic diameters between 0.3 μm and 1.0 μm (PM[0.3–1.0] ), between 1.0 μm ...
