Abstract

A case of a 58-year-old woman with occasionally diagnosed persistent atrial fibrillation (AF) is presented. The patient for many years experienced palpitations relived by oral propranolol treatment. After electrical cardioversion of AF to sinus rhythm prolongation of the QTc interval up to 520 ms became evident. Molecular screening of LQTS-related genes revealed the presence of R231S mutation in the KCNQ1 gene.
