“In atrial myocytes adenosine has a small inhibitory effect on basal L‐type calcium current (ICa, L ), but no effect on T‐type calcium current (ICa,T).”
“This indirect cAMP‐dependent mechanism of action has been shown to be responsible for the inhibition by adenosine of isoproterenol‐stimulated ICa, L , delayed rectifier K+ current (IK), chloride current (ICl), the transient inward current ITi, and the pacemaker current IF.”
