A New Method for Change Point Detection Developed for Sleep Stage Reconstruction From Heart Beat Statistics

Abstract

Sl'MMARY: Wo suggest a novel method for diango-point dctection äs a tool to localise trunsitions between sleep stages. The method analyscs timc series of heartbeat intervals, which are derived from the ECG-charmel of polysomnografic whole night recordings of healthy young probands. The algorithm, a modification of t ho detrendcd tluctuation analysis (DFA) progressively analyses the data points and thus admits "on-line" screening ofthe data set, e.g. with rcspcct to regions of non-REM vs. REM sleep.Brought to you by | Biblioteca de la Universidad de Sevilla Authenticated Download Date | 6/17/15 9:23 AM
