Figure 2. Risk of atrial fibrillation with air pollution.

Figure 2

Percent increase in the occurrence (odds) of AF episodes associated with increase in air pollution (PM2.5, black carbon, and NO2) as a function of moving average in hours prior to event. Stronger increased odds were found with shorter exposure periods before the AF event with the strongest odds in the 2 hour moving average.
