Can central aortic pressures be accurately estimated from radial tonometry using a generalized transfer function?
Radial tonometry combined with a generalized transfer function provides an accurate non-invasive method to estimate central aortic pressures and arterial compliance.
Central aortic pressures can be accurately estimated from radial tonometry with the use of a generalized TF. The reconstructed waveform can provide arterial compliance estimates but may underestimate the augmentation index because the latter requires greater fidelity reproduction of the wave contour.
