Abstract

Sinus node dysfunction is the most common indication for antibradycardiac permanent pacing after heart transplantation. Lack of atrioventricular synchrony during pacing can result in symptoms ranging from mild chest discomfort to severe manifestations such as dyspnea, hypotension, and cardiovascular collapse, all of which are ascribed to pacemaker syndrome. In infants pacemaker syndrome is often only recognized in the face of marked hemodynamic compromise. This report details an unusual account of pacemaker syndrome in an infant after orthotopic heart transplantation. Careful assessment of atrioventricular synchrony is important after infant transplantation.
