[Atrial tachycardia with block in congenital atrial septal defect. A case report].
Atrial arrhythmia is not uncommon in congenital atrial septal defect. Its incidence increases with age and the hemodynamic compromise of right ventricle. In the literature, atrial fibrillation is the most common presentation in middle-aged adults with congenital atrial septal defect, followed by atrial flutter and paroxysmal supraventricular tachycardia. However, atrial tachycardia with block has rarely been reported. We here report a case of 61-year-old male with congenital secundum atrial septal defect who presented atrial tachycardia with block without taking digitalis. Normal sinus rhythm restored after six-day use of Verapamil and Quinidine.
