Abstract
Atrial fibrillation is an arrhythmia characterised by disorganised atrial depolarisations resulting in uncoordinated atrial activity, a reduction in cardiac output, and a number of other significant health risks. There are three possible therapeutic goals to consider for patients with atrial fibrillation: control of ventricular rate, maintenance of sinus rhythm, and prevention of thromboembolism1. Present treatments for atrial fibrillation include drug therapy, ablation and pacing, and external cardioversion. All of these treatments vary in their method, invasiveness, and therapeutic goal. Recent studies have shown that a new technique of low-energy internal cardioversion with temporary leads is a feasible and effective method for restoring sinus rhythm2–4. Given the recurrent nature of atrial fibrillation, the promising results with low-energy internal cardioversion, and the present state of implantable device technology and application, the possibility has been raised for the development of an implantable atrial defibrillator. Levy and Camm discussed the basic requirements for an implantable atrial defibrillator in an editorial examining the feasibility of such a devices5. The authors concluded that safety, efficacy, and tolerability were the main concerns in developing a device to terminate atrial fibrillation. Design concepts should,therefore, incorporate these concerns. This chapter will specifically address these criteria in the context of the present status of basic research and clinical experience.
