Abstract

This report discusses the use of temporary transvenous external cardiac pacing during cardiac magnetic resonance imaging (MRI). Despite its feasibility having been explored in adults, its application in pediatric patients is not well established. We present a case of a 6-year-old female with a high-degree atrioventricular (AV) block managed with an externalized temporary pacing system for MRI. This system enabled cardiac MRI for further treatment planning, eliminating the immediate need for permanent pacemaker implantation. This case underscores the feasibility of conducting cardiac MRI in pediatric patients requiring temporary pacing, contingent upon the utilization of appropriate equipment and protocols.
