In a larger study of approximately 200 Boston-area ICD patients, we found a nonstatistically significant increased risk of ventricular arrhythmias (confirmed by an electrophysiologist) associated with 2-day mean N[O.sub.2], particulate matter < 2.5 [micro]m in aerodynamic diameter (P[M.sub.2.5]), black carbon, carbon monoxide, ozone, and sulfur dioxide (Dockery et al.
