Abstract

This is a case of flecainide toxicity in a patient with a permanent pacemaker. This case not only highlights the effects of flecainide toxicity on surface electrocardiography but how toxicity effects pacemaker function and its ability to transvenously pace the heart. The report provides some discussion of the management options for flecainide toxicity. (Level of Difficulty: Beginner.).

Keywords: ECMO, extracorporeal membrane oxygenation; Na+, sodium; SVT, supraventricular tachycardia; electrocardiography; flecainide; toxicology.
