Indications for implantation of a dual-chamber pacemaker combined with an implantable cardioverter-defibrillator.

Of 122 patients with single-chamber implantable cardioverter-defibrillators (ICDs) reviewed retrospectively, 35 had traditional indications, 14 had other indications, and 18 had ICD-specific indications for dual-chamber pacing therapy. Thus, 67 patients (55%) were potential candidates for dual-chamber pacing, which has only recently become available combined with ICD therapy.
