From: Nitroprusside modulates pulmonary vein arrhythmogenic activity
Effect of nitroprusside on transient inward current (I ti ) in PV cardiomyocytes. Current traces of transient inward current indicated by blank triangle before (upper panel) and after (lower panel) the administration of nitroprusside in a PV cardiomyocyte. There was decreased transient inward current after nitroprusside. The transient inward current was induced from repolarization to -40 mV after a depolarizing pulse (from -40 to +40 mV for 3 s, see inset for clamp protocol).
