title: Exercise-induced bradycardia after Mustard repair for complete transposition.
abstract: Impairment of sinus rhythm has been reported after the Mustard procedure for complete transposition. We observed two patients who developed severe bradycardia during or after exercise. The first had a 2.8 s sinus pause in the recovery period, the second had a drop in heart rate during exercise. Both eventually had a pacemaker implanted. Exercise testing can be helpful in detecting sick sinus syndrome.
