Evaluation of electrocardiographic parameters in patients with hearing loss genotyped for the connexin 26 gene (GJB2) mutations.

Abstract excerpt

INTRODUCTION: Several studies have associated congenital sensorineural hearing loss in children with prolongation of the cardiac parameter QTc. The cause of this association is unknown. At the same time, mutations in GJB2, which encodes connexin 26, are the most common cause of congenital hearing impairment. OBJECTIVE: To compare electrocardiographic parameters (PR interval, QRS complex, and QTc interval) in...
