  Purpose

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.

Primary Outcome Measures:
  • Unplanned hospital admissions for cardiac reasons OR Death of cardiovascular causes OR progression to chronic atrial fibrillation [ Time Frame: 3 years from randomization (39 months total) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Sensitivity and Specificity of automatic AT/AF detection [ Time Frame: 3 years from randomization (39 months total) ] [ Designated as safety issue: No ]
  • In hospital costs [ Time Frame: All in hospital costs 3 years from randomization (39 months total) ] [ Designated as safety issue: No ]
  • Total number of hospitalizations after 3 years [ Time Frame: 3 years from randomization (39 months total) ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Device managed arm
Device-managed therapy arm. Shock therapy for atrial arrhythmias is delivered automatically from the device.
Device: Dual (atrial and ventricular) implantable defibrillator
The devices automatically applies therapy (shock) for atrial fibrillation, when atrial fibrillation is confirmed.
Active Comparator: Traditional arm
Traditional therapy arm. In this arm, therapy for atrial arrhythmias will be delivered from the device through command of the physician and in a hospital environment. Therefore, patients who will experience symptoms at home, will refer to their center, eventually hospitalized and treated for atrial arrhythmias.
Device: Dual (atrial and ventricular) implantable defibrillator
In hospital application of anti arrhythmic therapies via the device
Device: Dual (atrial and ventricular) implantable defibrillator
Therapy for atrial arrhythmias will be delivered from the device through command of the physician and in a hospital environment

  Eligibility

Ages Eligible for Study:   18 Years and older

Criteria

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
