Poincaré Plots illustrate the heart rate variability under four conditions: basal, rest, VR and mannequin-based simulations. Each scatter plot represents the relationship between consecutive NN intervals (NNi and NNi + 1, in ms) as measure of autonomic regulation, providing a visual depiction of autonomic regulation and stress responses.
