Tachyarrhythmias after pediatric heart transplantation

Our experience suggests that the presence of tachyarrhythmias after pediatric heart transplantation is not rare and usually not associated with rejection. Pediatric heart transplant recipients have a higher incidence of ectopic atrial tachycardia (EAT) than their adult counterparts. Most tachyarrhythmias resolve after a relatively brief period of medical treatment and recurrence is uncommon.
