Figures
The images for Figs 1 to 3 and 5 to 7 are incorrectly switched. The image that appears as Fig 1 should be Fig 7, the image that appears as Fig 2 should be Fig 5, the image that appears as Fig 3 should be Fig 6, the image that appears as Fig 5 should be Fig 3 and the image that appears as Fig 6 should be Fig 2. The figure captions appear in the correct order. The authors have provided a corrected version of figures here.
sECG: raw ECG signal, sdECG: denoised ECG signal, (zts, zte): start and end of good quality signal zones, (znts, znte): start and end of good quality signal combined with normal cardiac rhythm zones, sEDR: EDR series, (ets, ete, c): start, end and class of abnormal events (apnea or hypopnea), TST: total sleep time, AHI: apnea-hypopnea index.
R peak, QRSonset and QRSoffset are key points in an ECG beat, whereas QRS height, QRS width and RR interval are computed using the previous key points.
Top: raw ECG signal in black with baseline wander in red; down: denoised ECG signal. X-axis is the time scale in seconds.
In red, an abnormal beat zone to be suppressed for the rest of the analysis. X-axis is the time scale in seconds.
From top to bottom: HRV series, RWA series and denoised ECG signal. X-axis is the time scale in seconds.
n: number of patients.
