Educational Pearls:

  • SVT: supraventricular tachycardia

    • Pharmacotherapy for SVT includes drugs that block the AV node, such as adenosine

  • EKG criteria before adenosine administration in SVT

  1. Regular rhythm

  2. Monomorphic: ​​all QRS complexes are identical

  • If the EKG is polymorphic, with QRS complexes displaying changing morphologies, it is unsafe to administer adenosine

    • Adenosine can worsen polymorphic VTach and lead to VFib
