Figure 2.
Inward rectifier currents in RA and LA myocytes from SR, pAF, and cAF at −100 mV and −10 mV, respectively. Values are mean±SEM. A, Basal current in absence of CCh (2 μmol/L). B, Total current (basal current+CCh-mediated current increase) in presence of CCh. Numbers indicate myocytes per patient. *P<0.05 and #P<0.05 versus corresponding values in SR and pAF, respectively. §P<0.05 versus corresponding values in RA.
