Abstract
The Implantable Cardioverter Defibrillator （ICD） performs the functions of both a defibrillator and a pacemaker. Recent progress in ICD technology has been so remarkable that the device’s indications have had to be expanded to include implantation in children. It is therefore necessary to think about problems specific to pediatric implantation, such as growth, long-term follow-up, and complications related to children’s high activity levels and small bodies. ICD indication and the optimal implantation method must be determined through examination on a case-by-case basis.Cardiac Resynchronization Therapy （CRT） has been noted as a new non-drug therapy for refractory congestive heart failure, and some case reports on congenital heart disease in children have indicated that CRT was effective.
