Cardiac rhythm abnormalities during intravenous immunoglobulin G(IVIG) infusion in two newborn infants: coincidence or association?

Abstract

We report the occurrence of supraventricular tachycardia during intravenous immunoglobulin (IVIG) infusion. Supraventricular tachycardia was observed in two newborn patients during IVIG infusion. Both of the babies responded to adenosine treatment. Cardiorespiratory monitoring during IVIG infusion can be recommended because of the possibility of this potentially lifethreatening adverse effect.
