Adenosine
•Mechanism of action:
Activates Gi protein → inhibition of adenylate cyclase → ↓ cAMP → deactivation of L-type Ca2+ channels and activation of K+ channels → ↓ Ca2+ and ↑ K+ efflux → hyperpolarization → transient AV node block (short acting, approx. 15 seconds) → acute termination of supraventricular tachycardia

Digoxin
•Mechanism of action:
Inhibits Na+/ k+-ATPases → higher intracellular Na+ concentration → reduced efficacy of Na+/ Ca2+ exchangers → higher intracellular Ca2+ concentration → increased contractility, decreased heart rate.
