From: Nitroprusside modulates pulmonary vein arrhythmogenic activity
Effect of nitroprusside on delayed rectified outward potassium current (I K ) in the PV cardiomyocytes (n = 11). Current traces (upper panel) and I-V relationship (lower panel) of IK in the PV cardiomyocytes. Insets show the various clamp protocols. *P < 0.05, **P < 0.01, ***P < 0.005, versus before nitroprusside PV cardiomyocytes.
