Intravenous Epinephrine Infusion Test in Diagnosis of Catecholaminergic Polymorphic Ventricular Tachycardia

Epinephrine Infusion in Diagnosis of CPVT. Introduction: A test involving intravenous infusion of epinephrine has been proposed as a method alternative to exercise stress test in diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT). We aimed at estimating the predictive value of intravenous epinephrine administration in CPVT patients with frequent exercise‐induced ventricular ectopy. Methods and Results: We recruited 81...
