Medtronic single chamber icda listing of pacing leads approved for use with medtronic icds. the atrioventricular (dual-chamber) icd (av-icd), approved by the food and drug administration (fda) in 1997, is indicated for patients who are at risk for ventricular tachyarrhythmias and also in need of pacing for bradycardia (5 ; 6). patients without an apparent need for dual-chamber capability at the time of implant, the optimal approach to initial device selection—single- versus dual-chamber—has not been investigated.

only single chamber icds with a traditional lead that enable physicians to continuously monitor, diagnose, and manage atrial fibrillation (af) patients. by contrast, the choice of an av-icd removes this risk entirely. therefore, it is the primary -- and hopefully most frequent -- task of the icd to give you confidence that your heart is not beating too rapidly or too slowly on its own accord.
designwe developed a decision analytic model to estimate the economic costs of three alternative implantation strategies in icd recipients who do not demonstrate the need for a dual-chamber device at time of implant: 1) initial implantation of a single-chamber device in all patients with later upgrade to an av-icd as clinically needed; 2) initial implantation of an av-icd in all patients; and 3) targeted initial device selection on the basis of the results of electrophysiologic testing. many patients demonstrate the need for dual-chamber capabilities at the time of initial icd implantation, others develop sinus node dysfunction, av nodal conduction disease, or atrial arrhythmias later, thereby necessitating upgrade to a dual-chamber device. is not a complete list of our previously marketed implantable cardioverter defibrillators (icd).
