Table 4 Odds ratios (95% CI) for the association between the occurrence of an appropriate ICD discharge and an interquartile range increase in 24 h mean air pollutant concentrations (n = 1919). Results were adjusted for 24 h mean temperature, relative humidity and barometric pressure

From: Do acute changes in ambient air pollution increase the risk of potentially fatal cardiac arrhythmias in patients with implantable cardioverter defibrillators?
