(a) Short-term variability of monophasic action potential duration measured at 90% repolarization (STV-MAP) and (b) triangulation (APD₉₀−APD₃₀) at various time points in rabbits that had TdP (TdP present, n=4) and those that did not (TdP absent, n=3) in the group given clofilium and phenylephrine. Values are mean±s.e.mean. ^*P<0.05 compared with baseline, one-way ANOVA.
