摘要/Abstract

摘要： 采用盲系统辨识技术可以通过两路外周动脉压力波形重建主动脉波形，但如何选择外周动脉需要进行研究.本文使用基于子空间方法的盲系统辨识算法，同步采集人体左右两侧的桡动脉压力波形和足背动脉压力波形，按照4种不同组合进行主动脉压力波形重建，使用动态时间规整方法评判重建效果，确定外周动脉波形辨识的最优组合.结果表明，足背动脉与桡动脉组合对主动脉压力波形重建无显著性影响(P>0.5)，而仅使用桡动脉或足背动脉无法有效重建.

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
