Cardiac arrhythmias in children.

Recent interest in cardiac arrhythmias in children has been stimulated by a growing awareness of primary rhythm disorders in children, by the appearance of rhythm disorders following repair of many congenital heart defects, and by recent developments in clinical electrophysiology. This chapter focuses on developmental clinical cardiac electrophysiology, the spectrum of tachycardias in children, and the frequency, mechanism, and therapeutic decisions regarding cardiac arrhythmias in children who have had surgery for congenital heart disease.
