Effects of arginine vasopressin (AVP) on the late sodium current (INa-Late) in pulmonary vein (PV) cardiomyocytes with and without AVP (1 μM) or OPC 21268 (0.1 μM). An example and the average data of the INa-Late from (a) control (n = 12) and from PV cardiomyocytes treated with either (b) AVP (1 μM, n = 12), (c) OPC 21268 (0.1 μM, n = 9), or (d) AVP (1 μM) plus OPC 21268 (0.1 μM) (n = 11). INa-Late was measured as the tetrodotoxin (TTX)-sensitive current during ramp pulse from + 20 mV to − 100 mV. *P < 0.05
