Chronic β-blockade is associated with a reduction in the density of human atrial ITO, but not IKSUS. (A) Representative current traces of ITO and IKSUS in isolated atrial myocytes from a patient treated (●) or not treated (○) with a β-blocker. (B) Mean±SEM current-voltage-relationship for ITO density (●: n=30 myocytes, 15 patients, ○: n=32 myocytes, 14 patients) (C) Mean±SEM peak ITO and IKSUS densities at +60 mV. *=p<0.05; NS= not significant (p>0.05).
