Figure 1From: Effects of anti-malarial drugs on the electrocardiographic QT interval modelled in the isolated perfused guinea pig heart systemRelationships between QaTc changes and concentrations of quinidine (A), quinine (B), halofantrine (C), and mefloquine (D) in the isolated perfused guinea pig heart system. Each bar represents the mean ± SEM (n = 3 - 4). *Statistically significant compared with the same concentrations of quinine (p < 0.05).Back to article page
