Cardiorespiratory coherence analysis of abnormal heart rate responses during deep breathing

摘要

Although the heart rate variability (HRV) normally is highly synchronised with respiration during deep breathing, in patients with transthyretin amyloidosis we occasionally observe abnormal heart rate responses due to subtle arrhythmias. This study evaluates the use of cardiorespiratory coherence analysis for automatic detection of these abnormal patterns.
