Reduced Risk for Inappropriate Implantable Cardioverter-Defibrillator Shocks With Dual-Chamber Therapy Compared With Single-Chamber Therapy: Results of the Randomized OPTION Study (Optimal Anti-Tachycardia Therapy in Implantable Cardioverter-Defibrillator Patients Without Pacing Indications)

Study Questions:

Does dual-chamber implantable cardioverter-defibrillator (ICD) implantation in patients without pacing indication result in fewer inappropriate shocks than single-chamber ICD?
