Summary
Uncontrolled asthma is associated with reduced HRV and altered autonomic balance compared to controlled asthma. Longer asthma duration correlates with greater autonomic dysfunction.
Methods
Cross-sectional HRV comparison in controlled vs uncontrolled asthma
Key Findings
- Uncontrolled asthma associated with lower overall HRV
- Enhanced parasympathetic modulation in controlled asthma
- Longer asthma duration = greater autonomic changes
- Beta-agonist use affects HRV measurements
- Well-controlled asthmatics similar to healthy controls
Limitations
Medication effects complicate interpretation
What This Means for You
If you have asthma, good disease control may help preserve autonomic function. Chronically low HRV might indicate suboptimal control— discuss with your pulmonologist.
