FIGURE 6.
Right aERP after drug treatment. The aERP was measured at different pacing rates before and after the infusion of drugs: saline (A), dofetilide (B), ranolazine (C), and the combination of dofetilide and ranolazine (D). A, Only 2 horses cardioverted within the time of the experiment, therefore, n = 8 at the baseline and n = 2 in the saline group. B, One horse did not cardiovert within the time of the experiment and 1 horse had unstable placement of the electrode: n = 6. C, n = 8. D, One horse did not cardiovert within the time of the experiment: n = 7.
