From: Nitroprusside modulates pulmonary vein arrhythmogenic activity
The current tracings and I-V relationship of the L-type calcium current (I Ca-L ) of the control and nitroprusside-treated PV cardiomyocytes (n = 6). The ICa-L in the nitroprusside-treated PV cardiomyocytes was smaller than that in the control PV cardiomyocytes. The insets of the current tracings show the various clamp protocols. *P < 0.05, **P < 0.01, versus before nitroprusside PV cardiomyocytes.
