A Case of Congenital Complete Atrioventricular Block Treated with Transdermal Tulobuterol

摘要

Congenital complete atrioventricular block (CCAVB) is a condition in which the atria and ventriclesbeat independently of each other. CCAVB cases require permanent pacemaker implantation untiladulthood. Nevertheless, consensus regarding postnatal medical therapy for bradycardia has not beenreached. Here we report the case of a newborn with CCAVB, whose intractable bradycardia wassuccessfully treated with transdermal tulobuterol. Tulobuterol is a selective ?2-adrenoceptor agonist,widely used safely as bronchodilator in children. It also has positive inotropic and chronotropic effect via?1-adrenoceptors. We believe the tulobuterol patch can be used as an optional therapy for CCAVB wherepacemaker implantation is not available.
