Etiology of arrhythmias in congenital heart disease

Bradycardia	Examples
Congenital
Congenital sinus node dysfunction	Situs inversus
Congenital AV block	AV canal defects; cc-TGA
Acquired
Acquired sinus node dysfunction	s/p repair of Mustand/Senning, Fontan, Glenn or sinus venosus ASD
Acquired AV node dysfunction	s/p VSD/LVOT/aortic valve operation
Tachycardia	Examples
Congenital
Twin AV nodes	Heterotaxy syndrome
Acquired
Atrial tachycardia/flutter	Atrial baffles; post-MAZE
Atrial fibrillation	ASD's, mitral valve disease
Ectopic atrial tachycardia	Fontan

AV: atrioventricular; cc-TGA: congenitally corrected transposition of the great arteries; ASD: atrial septal defect; VSD: ventricular septal defect; LVOT: left ventricular outflow tract.
