Effect of nifedipine on action potential characteristics. (A) Example recordings from cells exposed to nifedipine. (B) The average relative (±SD, n = 4) change of APD50, APD90, and CL in response to nifedipine in Cor.4U cells with values corrected for differences in spontaneous rate. (C) Relative change of APD50, APD90, and CL in response to nifedipine in iCell Cardiomyocytes with values corrected for differences in spontaneous rate.
