The signal transduction of cardiac muscle contraction. Note that norepinephrine and epinephrine bind to β1 and β2-receptors, which activates Gs which activates adenylyl cyclase, but acetylcholine and adenosine bind to muscarinic type 2 and adenosine type 1 receptors, which activates Gi protein which inhibits adenylyl cyclase.
