To investigate possible effects of adrenergic stimulation about G proteinCactivated inwardly rectifying K+ channels (GIRK), acetylcholine (ACh)-evoked K+ current, IKACh, was recorded from adult rat atrial cardiomyocytes using the whole cell patch clamp method and a fast perfusion system. of Rp-cAMPS (a cAMP analogue that is inhibitory to PKA) mimicked the 2-adrenergic effect. The possibility… Continue reading To investigate possible effects of adrenergic stimulation about G proteinCactivated inwardly
