  Purpose

The goal of APART is the assessment of the therapeutic and preventive stimulation algorithms of the Medtronic AT500 and following devices in patients with atrial tachyarrhythmias and an indication for cardiac pacing according to the German guidelines. Medication is controlled throughout the study with a beta-blocker as the only antiarrhythmic drug.

Primary Outcome Measures:
  • Incidence of symptomatic and/or persistent re-occurrences of atrial arrhythmias [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Time to first re-occurrence of first symptomatic or persistent atrial arrhythmia [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Atrial fibrillation (AF)-burden [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Time interval between persistent episodes during the follow-up period [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Reduction of the total amount of tachyarrhythmias stored in the event counter of the implanted device [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Quality of life [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Necessity and date of a specific antiarrhythmic therapy and/or prescription of antiarrhythmic drugs class I and II [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Evaluation of possible atrial proarrhythmic effects of the termination algorithms [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Cost-efficiency [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Incidence in different pacing modes [AAI, DDD(R)] [ Time Frame: 2 years ] [ Designated as safety issue: No ]
