Abstract

We studied the incidence of the arrhythmia in 10 children with congenitally corrected transposition of the great arteries diagnosed during the period from May 1986 to July 1987. Patient age ranged from 1 to 15 years. On the 12 leads surface electrocardiogram, there were complete atrioventricular block in one child and wide P wave in two. On the 24-hour electrocar- diogram, there were sinus tachycardia in two children, sinus bradycardia in one, severe wandering pacemaker in two and severe sinus arrhythmia in two. Premature atrial contractions were found in 5 children and premature ventricular contractions in 4. The Lown’s grade of ventricular dysrhythmia were grade 1 in three children and grade 4A in one. In one patient with complete atrioventricular block, the morphologic pattern and the duration of QRS suggested a junctional rhythm.
