Most approaches for ECG-based detection of sleep apnea classify fixed-duration epochs (here: 60s) in a binary way with respect to the presence or absence of respiratory events. Identifying time-locked modulations in QRS-amplitude and respiratory myogram interference with a single feature, this paper presents a new method to transform such results into an estimate of the apnea-hypopnea-index (AHI). The basic idea is to translate the local period duration of the event-related quasi-periodic… CONTINUE READING
