The evolution of internal defibrillators.
ICDs have reduced mortality from SCD to 2% per year, which is a record unmatched by any other form of therapy. With continued evolution, ICD systems should become easier to implant, smaller, more effective in managing a variety of abnormal rhythms, and more comfortable for the patient. Implementation of technological innovations in future-generation devices should continue to extend the frontiers as clinicians consider ICDs for an expanding range of therapeutic applications.
