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

Figure 3

NOS3 knockout did not alter 𝐼_to or 𝐼_Ksus. (a) Representative current traces from WT and NOS3^−/− myocytes. (b) Summary data (mean ± S.E.M.) of 𝐼_toI-V curves in WT and NOS3^−/− myocytes. (c) Summary data (mean ± S.E.M.) of 𝐼_KsusI-V curves in WT and NOS3^−/− myocytes. 𝑛=7, 13 cells.
