Clin Exp Pediatr. 1996;39(10):1455-1460.   Published online October 15, 1996
Atrial flutter is a potentially life threatening complication of repair or palliation of congenital heart disease and is frequently drug resistant. Recent studies in human have demonstrated that common type atrial flutter is due to macro-reentry in the right atrium and that the reentrant circuit may involve slow conduction in the low posteroseptal area of the right atrium. Catheter ablation of atrial flutter has...
