Air Pollution Effects on Ventricular Repolarization

This report describes a study to explore novel electrocardiogram (ECG) parameters to improve our understanding of how air pollution may affect cardiovascular health. Drs. Robert Lux and Arden Pope used ECGs obtained in a previous study by Dr. Pope that found a decrease in heart rate variability associated with increased levels of particulate matter, and analyzed them for changes in novel parameters of another important potential change - ventricular repolarization.
