Defibrillation test in paediatric patients: should be done?

Abstract Funding Acknowledgements Type of funding sources: None. The defibrillation test (DFT) an implantable cardioverter-defibrillator (ICD) is performed to evaluate ventricular fibrillation detection and termination. In adults, routine testing for transvenous ICD less usually done as some studies found no advantages but potentially risks associated with. On the other hand, implantation ICDs in paediatric patients has different characteristics than adults. position coil will change with body’s growth could reflect changes vector. Also, reasons are (ventricular arrhythmias frequently adult’s myocardial infarction vs channelopathies, non-ischemic myocardiopathies congenital heart defects children young). There still lack information about utility DFT patients. Objective To describe who underwent , results follow-up. Methodology Retrospective cohort study 21 years old lasts 10 at a reference hospital. DFT, VF was induced by T wave shock, fast burst pacing or continuous direct current. Response evaluated. Patients failure terminate were defibrillated external defibrillator. Results 68 73 implantations (five replacements). Median age 13 old. youngest patient 2 oldest 72.6% (53/73) DFT. 90.6% (48/53) them, induced. two (4%, 2/48) did not VF. One these had Danon syndrome despite maximum energy discharged vector defibrillation; problem fixed replacement single lead dual system. arrhythmogenic cardiomyopathy detect During follow up, there 20 shocks appropriate (and successful). died because non-arrhythmic illness. Conclusions patients, useful ensure both adequate malignant arrhythmias, well their ability reverse them. Its performance affect 4% implants. Therefore, its recommended. be greater hypertrophic cardiomyopathy.
