Beluga - Clinical Observations of Automatic Algorithms for Cardiac Pacing

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00286858
Recruitment Status : Completed

Brief Summary:
This study shall evaluate in daily medical practice the clinical results of the AV delay hysteresis search algorithm in patients with a INSIGNIA ULTRA or AVT pacemaker implanted for one of the three following indications: sinus node dysfunction, atrial disease (or bradycardia/tachycardia) and atrio-ventricular paroxysmal block. In addition use and outcome of automatic functions will be evaluated.

Intervention Details:
  • Device: Insignia Ultra and Insignia AVT
    Regular AV-Delay increase to allow for intrinsic AV conduction, if present.

Primary Outcome Measures :
  1. Impact of Atrio-ventricular hysteresis algorithm on percentage of Ventricular pacing [ Time Frame: At 12 Months ]
    % Vp is compared between patients with atrio-ventricular hysteresis algorithm ON and OFF in patients with sino-atrial disease or paroxysmal AV block.
