Table 1.

The effect of temperature on transmural dispersion of action potential duration (APD90) recorded from isolated canine left ventricular tissue slices and arterially-perfused wedge preparations in the absence (control) and presence of E-4031 (1 μmol/L), chromanol 293B (293B, 30 μmol/L), or combination of these 2 agents. BCL = 2000 ms.
