• alpha-1 adrenergic receptors
• beta adrenergic receptors
• heart atrium
• cardiac inotropism
• inositolphosphates
• adrenergic receptor antagonists
• adrenergic agonists

AIM: To investigate whether stimulation of β-adrenoceptor (AR) and its subtypes augment α1-AR-evoked positive inotropic response and inositol phosphate (InsP) accumulation in isolated rat left atria.
