Implantable cardioverter-defibrillator shock prevention does not reduce mortality: A systemic review
2012, Heart RhythmCitation Excerpt :Many antiarrhythmic medications have been clearly shown to increase all-cause mortality,14,15 and although amiodarone appears to have a neutral effect on all-cause mortality in patients without an ICD,4 it has significant extracardiac toxicity that may be fatal.4,16,17 There is also the concern that amiodarone could increase defibrillation threshold in ICD patients,37–39 thereby reducing some of the benefit of ICD therapy in this population. Catheter ablation is associated with a variety of periprocedural complications and has a 3% procedure-related mortality rate,20,40 although there were no periprocedural deaths in the trials included in this analysis.
Antiarrhythmic drug therapy for new-onset ventricular arrhythmia (VT/VF) in ICD patients
2011, Cardiac Electrophysiology ClinicsCitation Excerpt :AAD drug therapy may slow the rate of ventricular arrhythmia, making it more hemodynamically tolerable and amenable to termination by ATP before a shock is delivered. Certain AAD (sotalol and dofetilide) also reduce the defibrillation threshold (DFT) and may help in easier termination of ventricular arrhythmia.58–61 AAD therapy may cause slowing of ventricular arrhythmia and, if the rate is slower than the programmed ICD detection rate, may result in failure to deliver therapy.
