Aortic pulse wave reflects cardiovascular status, but unlike the peripheral pulse wave, is difficult to be measured reliably using non-invasive techniques. Therefore, the estimation of aortic pulse wave from peripheral ones is of great significance. Traditional methods using generalized transfer functions suffer inter-subject and intra-subject variability of the cardiovascular system. This study proposed an adaptive transfer function method to estimate the aortic pulse wave from the brachial pulse wave.
