Objectives:
To explore associations between glucose metabolism and an EEG-independent measure of sleep quality, the sleep spectrogram, which maps coupled oscillations o heart-rate variability and electrocardiogram (ECG) derived respiration.

Conclusions:
The ECG-spectrogram analysis of sleep quality may provide information beyond that obtained by conventional polysomnography (PSG) in relationship to glucose metabolism.

Practical Significance:
ECG-derived sleep spectrogram measures of sleep quality are associated with alterations in glucose-insulin homeostasis. This could improve our understanding of sleep and sleep-breathing effects on glucose metabolism.
