Objectives:
To examine the utility of an electrocardiogram-derived sleep spectrogram to provide a different view of sleep.
Conclusions:
Non-electroencephalogram (EEG) recordings can provide an alternative approach to viewing sleep quality.
Practical Significance:
Novel insights into physiology and pathology of sleep can be obtained through the coupling of ECG and respiratory signal influences on the ECG R wave.
