Table 1 Number of detected sequences with cardiorespiratory coordination. Median and inter-quartile range during night-time sleep of the following parameters: N R total number of coordinated R-peaks, N seq total number of coordinated sequences, % N R relative amount of coordinated R-peaks with respect to the total number of R-peaks.
