Adenosine is a purine nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a β-N9-glycosidic bond. Adenosine is widely found in nature and plays an important role in biochemical processes, such as energy transfer — as adenosine triphosphate (ATP) and adenosine diphosphate (ADP) — as well as in signal transduction as cyclic adenosine monophosphate (cAMP). It is also a neuromodulator, believed to play a role in promoting sleep and suppressing arousal. Adenosine also plays a role in regulation of blood flow to various organs through vasodilation.
In addition to adenosine's endogenous forms, it is also used as a medication, specifically, as an antiarrhythmic agent, to treat a number of forms of supraventricular tachycardia that do not improve with vagal maneuvers. Common side effects include chest pain, feeling faint, shortness of breath along with tingling of the senses . Serious side effects include a worsening dysrhythmia and low blood pressure. It appears to be safe in pregnancy.
This video demonstrates one patient's experience with intravenous adenosine for supraventricular tachycardia. Follow-up: An electrophysiology study was performed which was remarkable for AVNRT which was successfully ablated without complications.

An elderly man (over 100 years old) presented to the A&E; department with cyanosis up to the mid shin and forearm bilaterally. He was severely hypovolemic. The paramedics treating him though his ECG showed a VT. The A&E; doctor noted an RSR pattern in V2 and diagnosed an SVT with right bundle branch block. The response to adenosine shown in this video strongly supported the diagnosis. The patient was given IV fluids and recovered.
Adenosine is a class V antiarrhythmic that's commonly administered to patients experiencing tachycardia.
