The use of definitive pacemakers (DPM) in children is rare, with surgical lesion of the conduction system being the main reasons for their implantation
Permanent postoperative bradyarrhythmias have been associated to high morbidity due to arrhythmias with hemodynamic involvement
The current study was developed aiming at analyzing the long-term evolution of patients with DPM due to postoperative bradyarrhythmias and to identify risk factors for death
Summary
The use of definitive pacemakers (DPM) in children is rare, with surgical lesion of the conduction system being the main reasons for their implantation. Permanent postoperative bradyarrhythmias have been associated to high morbidity due to arrhythmias with hemodynamic involvement. Postoperative atrioventricular blocks, in particular, are associated to high mortality even in patients submitted to corrections considered complete [1]. Permanent artificial heart pacing significantly reduces the death in these patients, giving an adequate long-term evolution. Mortality is generally related to the underlying disease and rarely to dysfunction of the pacing system. The current study was developed aiming at analyzing the long-term evolution of patients with DPM due to postoperative bradyarrhythmias and to identify risk factors for death
