Intravenous amiodarone therapy for rapid atrial fibrillation induced QT prolongation and torsades de pointes requiring recurrent cardioversion and temporary pacing in a 71-year-old woman.
Intravenous amiodarone therapy for atrial fibrillation can induce QT prolongation and torsades de pointes requiring acute intervention.
IV amiodarone for atrial fibrillation warrants QT monitoring; this single case leaves open the true incidence of torsades.
The case of a 71 year-old woman with rapid atrial fibrillation who underwent electrical cardioversion and amiodarone therapy. QT interval prolongation was observed with the development of torsades de pointes that required recurrent electrical cardioversion and temporal pacemaker implantation.
