TReatment of Atrial Fibrillation With Dual dEfibrillator in Heart Failure Patients

TReatment of Atrial Fibrillation With Dual dEfibrillator in Heart Failure Patients

Demonstrate the efficacy of the device-based managed therapy to treat atrial tachycardia and fibrillation (AT/AF) in patients with CHF indication for implant of a CRT defibrillator and to demonstrate the advantage of automatic electrical therapy of atrial arrhythmias compared to an in-hospital approach for treatment of symptomatic AT/AF.

Inclusion Criteria:

• chronic symptomatic HF despite stable, optimal drug therapy
• indication for a cardiac resynchronisation device with defibrillator backup according to current guidelines
• patients implanted with cardiac resynchronization device with dual (atrial and ventricular) defibrillation capabilities

Exclusion Criteria:

• Chronic atrial fibrillation
• Valvular disease
• patients who underwent or are planned for ablation of atrial fibrillation
• cerebral vascular accident/transient ischemic attack within 12 months from implant which lead to relevant impairment
• preexisting unipolar pacemaker
