Abstract: Central aortic pressure wave(CAPW)can be reconstructed by different peripheral artery pressure waves(PAPW)non-invasively using blind system identification technology, but the selection of peripheral arteries remains a serious problem. In this paper, an aortic pressure wave reconstruction algorithm based on subspace method has been used. Radial pressure waves and dorsal pedal artery pressure waves are collected for reconstruction. The aortic pressure wave is reconstructed dynamically through four different combinations, and the results are assessed by dynamic time warping.The optimal combination of peripheral arterial waves is also determined.The results show that any combination of the dorsal and radial arteries pressure wave has no significant effect on the reconstruction of aortic pressure wave(P>0.5). However,the reconstruction cannot be achieved by only using the radial pressure waves or the dorsal pedal pressure waves.

Key words: blind system identification, subspace method, aortic pressure wave, peripheral arterial pressure wave, dynamic time warping
