In contrast, TWA provides information on the repolarizing current (specifically calcium cycling) during repolarization of the adjacent myocardial regions with discordant alternans (Narayan 2006), Thus, we tested the hypothesis that exposure to individual pollutants or the combination of both increases TWA in a subset of the same study population.
