Figure 3.

The correlation between measured CVP and estimated CVP in the validation cohort are shown in part A. The Bland-Altman plot for the comparison of measured CVP and estimated CVP in the validation cohort is shown in part B. There is a moderate positive correlation (r = 0.705) and good agreement (mean difference 1.15 ± 3.70 mmHg) between the measured CVP and estimated CVP. ‘Estimated CVP = 47.90−0.086 × (RA lead impedance) + 0.013 × (RV lead impedance)−0.020 × (LV lead impedance). CVP, central venous pressure; LV, left ventricular; RA, right atrial; RV, right ventricular; SD, standard deviation; SEE, standard error of estimate.
