Cognitive Behavioral Therapy for Paroxysmal Atrial Fibrillation: Heart Rate Variability, Physical Activity, and Sleep
Authors' conclusion
In this select cohort, AF-CBT decreased insomnia severity but had no impact on HRV or physical activity.
Study context
- Population
- Patients with symptomatic paroxysmal AF on optimal medical therapy (mean age 65.4 ± 8.3 years, 58% females, 61% on beta-blockers)
- Participants
- 65 vs 62
- Comparison
- Online AF-CBT vs AF education
- AF-CBTn = 65
- AF educationn = 62reference
Primary result
As reported in the abstract
- Objective and subjective physical activity and sleep duration unchanged after treatment, no significant difference between groups
- No changes in AF burden or heart rate variability (HRV) indices at rest during the day or at night
