Key result
Analysis of cardio-respiratory data using conditional recurrence probabilities revealed a clear coupling direction from the respiratory system to the heart rate, and from the heart rate to mean arterial blood pressure.

Does not warrant clinical practice changes; leaves open validation of recurrence plots for directional cardiorespiratory coupling.
Observational (n=11)
Joint recurrence plots can be used to identify directional coupling in the human cardiorespiratory system, demonstrating respiratory influence on heart rate and heart rate influence on blood pressure.
A 2013 study conducted an observational in Pregnancy and preeclampsia (cardiovascular variability) (n=11). Cardio-respiratory coupling analysis via conditional recurrence probabilities was evaluated on Coupling direction between respiration, heart rate, and mean arterial blood pressure. Analysis of cardio-respiratory data using conditional recurrence probabilities revealed a clear coupling direction from the respiratory system to the heart rate, and from the heart rate to mean arterial blood pressure.
