New Arrhythmia Study Findings Reported from Environmental Protection Agency

2011 AUG 1 -- "Diesel exhaust (DE), which is emitted from on-and off-road sources, is a complex mixture of toxic gaseous and particulate components that leads to triggered adverse cardio-vascular effects such as arrhythmias. We hypothesized that increased risk of triggered arrhythmias 1 day after DE exposure is mediated by airway sensory nerves bearing transient receptor potential (TRP) channels [e. g., transient receptor potential cation channel, member A1 (TRPA1)] that, when activated by noxious chemicals, can cause a centrally mediated autonomic imbalance and heightened risk of arrhythmia," scientists writing in the journal Environmental Health Perspectives...
