Figure 7From: Comparison of two different approaches in the detection of intermittent cardiorespiratory coordination during night sleepDependence on age. There is a remarkable decrease of mean PP with age (upper diagram) which results from a loss in autonomic modulation of heart rate: Decreased RSA leads to lower detection rates of coordinated sequences by binary pattern analysis and to an inaccuracy of coordination analysis, e.g. expressed by lower overall correlation between phase and pattern recurrency (lower diagram, see also r1 in Table 1).Back to article page
