Claim One:
1. A method of providing a graphical representation of sleep quality, comprising: obtaining ECG data for a patient in a sleep assessment module of a computer processing unit; obtaining a plurality of N-N intervals from the ECG data in the sleep assessment module by processing the ECG data to identify a plurality of normal beats and extracting the plurality of N-N intervals based on the identified normal beats; calculating in the sleep assessment module a plurality of spectral densities based on the plurality of N-N intervals, wherein each spectral density is associated with one of a plurality of successive time windows and is calculated based on certain ones of the N-N intervals associated with the one of the plurality of successive time windows; generating the graphical representation of sleep quality in the sleep assessment module based on the plurality of spectral densities by creating the graphical representation as a plot having a time axis and a frequency axis, wherein the graphical representation includes a plurality of images with each image being created based a respective one of the spectral densities by color coding each image in a manner wherein a particular color at each frequency value along the frequency axis is determined based on an associated power at that frequency from the spectral density from which the image was created; and displaying the graphical representation on a display device.
