Key result
Apnea significantly decreased rMSSD and nHF heart rate variability indices compared to normal respiration, indicating an imbalance in autonomic nervous system function.
Why the study?
Frequent cessations of respiration increase the risk of arrhythmia, which is modulated by the autonomic nervous system, but how apnea influences autonomic function using short-term HRV indices required analysis.
Does apnea alter short-term heart rate variability indices compared to normal respiration in healthy subjects and patients with sleep disorders?
Cross-Sectional (n=81)
Does apnea alter short-term heart rate variability indices compared to normal respiration in healthy subjects and patients with sleep disorders?
Apnea significantly alters short-term heart rate variability indices, reflecting an autonomic nervous system imbalance that may predispose individuals to arrhythmias.
No takes yet. Share an insight, caveat, or question.
Breath-holding alters short-term HRV in healthy volunteers; leaves open whether apnea contributes to arrhythmia risk via ANS imbalance.
He et al. (2020) conducted a cross-sectional in Apnea (n=81). Apnea vs. Normal respiratory state was evaluated on Short-term heart rate variability indices (including rMSSD and nHF). Apnea significantly decreased rMSSD and nHF heart rate variability indices compared to normal respiration, indicating an imbalance in autonomic nervous system function.
