Adenosine is indicated in the ACLS algorithm "[Adult] Tachycardia With a Pulse" for patients with

  • stable tachycardia and narrow QRS complex
  • stable tachycardia and regular and monomorphic but wide QRS complex (this presumes a supraventricular rhythm with an abnormal conduction pathway causing the wide QRS)
  • unstable tachycardia with narrow complexes (although synchronized cardioversion is also indicated and usually given first)


Adenosine temporarily slows conduction through the AV node, which may
