Adenosine
It is one of the naturally occurring nucleoside.
Action:
It causes a reduction in conduction velocity. It causes an increased refractory period and reduces automaticity in the AV node.

Its duration of action is short. Its half life is approximately 10 seconds.
Therapeutic uses:
Acute supraventricular tachycardia (IV administration)
Adverse effects:
Flushing, chest pain, dyspnea, hypotension
