Figure 6. Ventricular repolarization changes.
A, averaged recordings of the monophasic action potential in WT (black) and KO (red) hearts from females. B, female action potential durations (in milliseconds) at 20, 50, 70 and 90% repolarization in WT and KO mice; bar graph shows means ± SEM (n = 6), and *P < 0.05. C, averaged recordings of monophasic action potential in WT (black) and KO (red) hearts (n = 3) from males. D, male action potential durations (in milliseconds) at 20, 50, 70 and 90% repolarization in WT and KO mice; bar graph shows means ± SEM (n = 9), and *P < 0.05. Monophasic action potential recordings were obtained during perfusion at 37°C.
