BACKGROUND Heart rate variability (HRV), a measure of cardiac autonomic tone, has been associated with cardiovascular morbidity and mortality. Short-term studies have shown that subjects exposed to higher traffic-associated air pollutant levels have lower HRV. OBJECTIVE Our objective was to investigate the effect of long-term exposure to nitrogen dioxide(More)
BACKGROUND Disturbances of heart rate variability (HRV) may represent one pathway by which second-hand smoke (SHS) and air pollutants affect cardiovascular morbidity and mortality. The mechanisms are poorly understood. OBJECTIVES We investigated the hypothesis that oxidative stress alters cardiac autonomic control. We studied the association of(More)
