A method of REM-NREM sleep distinction using ECG signal for unobtrusive personal monitoring

Computers are used extensively in sleep labs for polysomnography and for assistance in sleep staging. However, the test is highly inconvenient to the patient and requires availability of specially equipped sleep labs. Alternative approaches that enable unobtrusive in-home sleep staging with ECG or other signals are highly desirable. In this paper we describe a method that can be used for distinction of REM and NREM sleep stages using spectral and non-linear features of ECG derived RR interval series.
