The beat-by-beat variability of heart period (RR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and skin microvascular conductance (G) in the palmar region of 23 healthy volunteers were analyzed during rest (R), clinostatic exercise at 10% maximum level (EXE1), 20% (EXE2) 30% (EXE3) and recovery (REC), G was obtained as the ratio between mean flow (laser Doppler) over one heart period and mean arterial pressure (Finapres). Exercise was accompanied ...
