Variables
Baseline
IHG
Baseline
IHG
SBP (mmHg)
DBP (mmHg)
MAP (mmHg)
HR (bpm)
Cardiac index (L/min/m2)
Stroke index (mL/beat/m2)
TPR (dyn/seccm-5m2)
Means SE, values are not adjusted for the influence of the covariates. , measures during IHG are different from baseline (main effect); , task by group interaction; , group differences in baseline hemodynamic variables. SBP: systolic blood pressure; DBP: diastolic blood pressure; MAP: mean arterial pressure; HR: heart rate; TPR: total peripheral resistance.
