| Abstract: | We present the analysis of physiological measurements from coronary patients during rehabilitation following a coronary event. A key feature we analyse is how different physiological systems interact. An increase in interaction strength reflects stronger integration between physiological systems, indicating effective recovery. We analyse signals recorded at the start of the rehabilitation and again after three months, allowing for monitoring changes during this critical period. The dataset includes signals of tissue oxygenation, blood flow, respiration, and electrocardiogram activity. We apply the recently developed cross-vector approach for characterizing interactions from measured time series. This is a nonlinear method based on reconstructed state-spaces. It is broadly applicable to various deterministic and stochastic dynamics. It reliably identifies both the strength and the direction of interactions even in short and noisy data. Applied to patient data, the method reveals changes in interaction strength and direction that may reflect underlying physiological changes. The resulting features hold promise for tracking rehabilitation progress at an early stage and for continuous monitoring during long-term rehabilitation. |
