Vol. 21, Issue 6 Validation of an Adaptive Transfer Function Method to Estimate the Aortic Pressure Waveform
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.
