Narrow-complex AV reentrant tachycardia (AVRT) and AV nodal reentrant tachycardia (AVNRT) are treated by blocking AV node conduction with the following:

  • Vagal maneuvers (eg, Valsalva maneuver, carotid sinus massage, splashing cold water or ice water on the face)
  • Adults: IV adenosine 6-12 mg via a large-bore line (the drug has a very short half-life)
  • Adults: IV verapamil 5-10 mg or diltiazem 10 mg
  • Pediatric patients: Adenosine and verapamil or diltiazem are dosed on the basis of weight.
