摘要

•An approach to analyze cardiovascular and respiratory couplings has been developed.•Temporal dynamics of couplings on 5 min segments during a head-up tilt test was studied.•Joint symbolic dynamics indices were obtained for couplings analysis.•Results highlighted reduced cardiovascular–respiratory couplings for patients.
