Sinus node dysfunction after surgical repair of an atrial septal defect (secundum-type): worth the wait.

Sinus node dysfunction after surgical repair of an atrial septal defect is a rather uncommon complication. We report a case of protracted post-operative sinus node dysfunction which was managed successfully by oral theophyllines and 'watchful' waiting. This strategy could avoid placement of a permanent pacemaker in this patient group of younger age.
