The line plots show examples of HP, SAP, DAP, and MSNA beat-to-beat variability recorded during T0 (A–D) and T60 (E–H). Fast dynamics at the respiratory rate are more visible in HP and SAP series during T0 (A,B) and in SAP during T60 (F). DAP and MSNA series (C,D,G,H) are dominated by rhythms at frequency slower than respiration.
