Thomas RJ, Mietus JE, Peng CK, et al. Impaired sleep quality in fibromyalgia: Detection and quantification with ECG-based cardiopulmonary coupling spectrograms. Sleep Med 2010; 11(5): 497-8. DOI: 10.1016/j.sleep.2009.09.003
Retrospective CardioPulmonary Coupling (CPC) analysis of Electrocardiogram (ECG) signals from polysomnogram (PSG) data (Electroencephalogram, EEG) from patients with fibromyalgia compared with matched controls.
Both ECG and EEG approaches yield consistent findings in this syndrome, further solidifying the hypothesis of altered sleep stability in fibromyalgia.
This study shows the favorable comparison of CPC findings over time with traditional PSG findings and the pain diaries of patients suffering from fibromyalgia.
