The SphygmoCor CPV is a time-consuming, user-dependent applanation tonometric method with ECG gating for PWVao measurement (27).
Its use requires trained personnel.
Existing cardiovascular outcome studies (33,34).
The device uses validated generalized transfer function (GTF) (28).
Invasively validated AIXao and SBPao (28,29,30).
PWVao is also validated invasively, however the limit of agreement according to Bland-Altman plot turned to be high -3.8 m/s (-2SD) and 4.1 m/s (+2SD) (31).
