Effects of NS5806 on the left ventricular APD and outward potassium currents of cardiomyocytes. (A) Representative AP traces at 1 Hz stimulation; (B) Summary data for APDs. (C) Representative current traces of the outward potassium currents recorded with the voltage protocol shown in the inset; (D) Average current density–voltage (I-V) relationships of the peak outward currents. n ≥ 15 cardiomyocytes from at least 5 mice in each group. *P < 0.05, ** P < 0.01 versus the Sham + Vehicle group. #P < 0.05, ##P < 0.01 versus TAC + Vehicle.
