Change in the odds of onset of symptomatic arrhythmia associated with a 10 μg/m3 (1 mg/m3 for CO) increase in air pollutant concentrations during lag 0 to 24 hours
| Pollutant | Change, % (95% CI) | |||
|---|---|---|---|---|
| Atrial fibrillation | Atrial flutter | Premature beats | Supraventricular tachycardia | |
| PM2.5 | 0.6 (0.2 to 1.1) | 3.0 (1.0 to 5.2)* | 0.2 (−0.5 to 0.9) | 1.7 (1.1 to 2.4) |
| PM2.5–10 | 0.4 (−0.1 to 1.0) | 3.6 (0.9 to 6.3) | −0.4 (−1.3 to 0.5) | 2.2 (1.4 to 3.1) |
| NO2 | 1.6 (0.8 to 2.4) | 5.0 (1.6 to 8.5) | 1.7 (0.5 to 2.9) | 4.1 (2.9 to 5.3) |
| SO2 | 2.6 (0.3 to 4.9) | 17.2 (6.1 to 29.5) | −1.6 (−5.0 to 1.9) | 5.6 (2.2 to 9.1) |
| CO | 5.7 (1.8 to 9.8) | 30.3 (9.8 to 54.8) | 2.2 (−3.6 to 8.4) | 10.9 (4.7 to 17.3) |
| O3 | 0.1 (−0.4 to 0.5) | 0.3 (−1.5 to 2.2) | 0.1 (−0.6 to 0.7) | 0.8 (0.2 to 1.4) |
Note: CI = confidence interval, CO = carbon monoxide, NO2 = nitrogen dioxide, O3 = ozone, PM2.5 = particulate matter with an aerodynamic diameter ≤ 2.5 μm, PM2.5–10 = particulate matter with an aerodynamic diameter between 2.5 and 10 μm, SO2 = sulfur dioxide.

This result was estimated using PM2.5 concentrations at a lag period of 2 days (49–72 h).
