Effect of pulmonary vein isolation on sleep breathing in people with paroxysmal atrial fibrillation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational study enrolling adults with paroxysmal atrial fibrillation who are scheduled for pulmonary vein isolation. Participants will undergo four polygraphic sleep recordings at defined timepoints before and after the ablation to measure hypopnea index and other sleep parameters. Clinical data on AF episodes and obstructive sleep apnea risk factors will be collected alongside routine care without introducing experimental treatments. Sleep breathing metrics will be compared over time to see if rhythm-control therapy is associated with measurable changes in sleep-disordered breathing.
