Prolonged Action Potential and After depolarizations Are Not due to Changes in Potassium Currents in NOS3 Knockout Ventricular Myocytes

Figure 2

𝐼_K1 current was not changed in NOS3^−/− myocytes. (a) Representative traces from WT and NOS3^−/− myocytes. (b) I-V curves of 𝐼_K1 in WT and NOS3^−/− myocytes. (c) Summary data (mean ± S.E.M.) of peak outward 𝐼_K1 in WT and NOS3^−/− myocytes. (d) Summary data (mean ± S.E.M.) of 𝐼_K1 slope conductance in WT and NOS3^−/− myocytes. 𝑛=6, 15 cells.
