Atrial flutter with flecainide-induced 1:1 conduction at a rate <200 b.p.m. at rest: a case report.

ABSTRACT:

Background

Class IC antiarrhythmic drug flecainide is commonly used in the management of atrial arrhythmias and in particular atrial fibrillation (AF). Although previously reported as a potential complication, atrial flutter (AFL) with 1:1 atrioventricular (AV) conduction is rare, with only few cases reported so far, most of which related to physical activity. In all previous reported cases, 1:1 conduction resulted in ventricular rates of >200 b.p.m.

Case summary

We report the case of a 60-year-old woman, who presented to our local emergency department with palpitations related to acute onset AF. The patient developed symptomatic 1:1 AFL with a rate of 192 b.p.m., shortly after administration of intravenous flecainide, which spontaneously converted back to AF and subsequentl
