Beat-to-beat Variability in Persistent Atrial Fibrillation — BVAR-Afib  

Persistent Atrial Fibrillation Clinical Trial

Official title:
Beat-to-beat Variability in Persistent Atrial Fibrillation

Clinical Trial Summary

Heart rate variability (HRV) in patients with atrial fibrillation (AF) is hardly studied. Though a reduced HRV in patients with heart failure and reduced ejection fraction (HFrEF) has been associated with poor prognosis. Data on HRV in AF-patients without a reduced ejection fraction is lacking. We hypothesize that those patients with persistent atrial fibrillation and larger beat-to-beat variability would be more symptomatic than does those with smaller HRV. To asses this theory we intend to perform a prospective observational trial. Symptoms of Atrial fibrillation will be assessed using Quality of Life questionnaires and 6 minutes walking test. Heart rate variability will be assessed using 24 hour Holter ECG monitoring.

The correlation between symptoms and heart rate variability will be then assessed.
