This study will look at the correlation between ventricular rate regulation (VRR) and the percentage of biventricular pacing as well as subjective quality of life and level of physical ability in CRT patients with atrial fibrillation.
To investigate whether VRR can increase the amount of biventricular pacing in CRT patients with conducted atrial arrhythmias. Secondarily, an investigation will be carried out to determine whether this increase in biventricular pacing results in an improvement in quality of life, as well as an improvement in the symptoms caused by the atrial arrhythmia and an improvement in the level of physical ability.

Percentage of Biventricular Pacing
Comparison of the average percentage of biventricular pacing in subjects randomised to Ventricular Rate Regulation (VRR) = ON to subjects randomized to VRR = OFF
Time frame: 6 month
Correlation Between VRR and the Subjective Quality of Life
Correlation between VRR mode and the subjective quality of life (QOL) measured by a QOL questionnaire in both randomized groups
Time frame: 6 Month
Correlation Between VRR and the Symptoms Caused by Conducted Atrial Arrhythmias
Correlation between VRR mode and conducted atrial arrhythmias (if observed) in both randomized groups
Time frame: 6 months
Correlation Between VRR and Physical Ability (6 Minute Walk Test, Optional Spiroergometry)
Correlation between VRR and physical ability in both randomized groups measured by a 6 minute walk test or an optional spiroergometry
Time frame: 6 months
