“…Nitrogen dioxide is a primary pollutant and strong respiratory irritant mainly from outdoor sources including motor vehicles and fossilfuel power plants, whereas the most important indoor sources are gas heaters, stoves and tobacco smoke 28 . Th e number of patients admitted to ED correlates with the concentration of NO 2 and PM 10 particles 8,10,24,[29][30][31] , which have strong infl uence on cardiovascular morbidity and mortality. In this study, the number of patients with arrhythmias was in positive correlation with the concentration of NO 2 and PM 10 particles on the day of ED admission.…”

SUMMARY -In this study, we investigated the correlation of air temperature, pressure and concentration of air pollutants with the rate of admissions for cardiac arrhythmias at two clinical centers in the area with a humid continental climate. Th is retrospective study included 3749 patients with arrhythmias admitted to emergency department (ED). Th ey were classifi ed into four groups: supraventricular tachycardia (SVT), ventricular tachycardia (VT), atrial fi brillation/undulation (Afi b/ Aund), and palpitations (with no ECG changes, or with sinus tachycardia and extrasystoles). Th e number of patients, values of meteorological parameters (average daily values of air temperature, pressure and relative humidity) and concentrations of air pollutants (particles of dimensions ~10 micrometers or less (PM 10 ), ozone (O 3 ) and nitrogen dioxide (NO 2 )) were collected during a two-year period ( July 2008-June 2010). Th ere were 1650 (44.0%), 1525 (40.7%), 451 (12.0%) and 123 (3.3%) patients with palpitations, Afi b/Aund, SVT and VT, respectively. Spearman's correlation yielded positive correlation between the occurrence of arrhythmias and air humidity on the day (r=0.07), and 1 (r=0.08), 2 (r=0.09) and 3 days before (r=0.09), and NO 2 particles on the day (r=0.08) of ED admission; palpitations and air humidity on the day (r=0.11), and 1 (r=0.09), 2 (r=0.07) and 3 days before (r=0.10), and PM 10 (r=0.11) and NO 2 (r=0.08) particles on the day of ED admission; and Afi b/Aund and air humidity 2 days before (r=0.08) ED admission (p<0.05 all). In conclusion, there was a very weak positive correlation of the occurrence of cardiac arrhythmias with air humidity and concentration of air pollutants in the region with a humid continental climate.

“…Ozone is a secondary pollutant created indirectly from combustion engines; it is related to hospital admissions for cardiovascular and respiratory diseases [21][22][23][24] . Several authors have reported positive association, whereas others found no association between arrhythmias and O 3 particles 25,26 .…”
