Arrhythmia induction using isoproterenol or epinephrine during electrophysiology study for supraventricular tachycardia

摘要

Background: Electrophysiology study (EPS) is an important part of the diagnosis and workup for supraventricular tachycardia (SVT). Provocative medications are used to induce arrhythmias, when they are not inducible at baseline. The most common medication is the beta 1-specific agonist, isoproterenol, but recent price increases have resulted in a shift toward the nonspecific agonist, epinephrine.
