Objectives:
Retrospective CardioPulmonary Coupling (CPC) analysis of Electrocardiogram (ECG) signals from polysomnogram (PSG) data (Electroencephalogram, EEG) from patients with fibromyalgia compared with matched controls.

Conclusions:
Both ECG and EEG approaches yield consistent findings in this syndrome, further solidifying the hypothesis of altered sleep stability in fibromyalgia. 

Practical Significance:
This study shows the favorable comparison of CPC findings over time with traditional PSG findings and the pain diaries of patients suffering from fibromyalgia.
