Bradycardia: a late complication following cardiac transplantation

Symptomatic bradycardia occurred in 11 of 213 patients (5.2%) surviving > 1 year after orthotopic heart transplantation, most of whom were managed with permanent pacemakers. Evidence for sinus and/or atrioventricular node dysfunction was present in many cases, but patients at risk for this complication could not be predicted from baseline clinical characteristics.
