Techniques for the Morphological Analysis of the Pulse Wave

Resumo

A new technique for contour analysis of the pulse wave signal is proposed. It is based on spectral analysis of a sequence of replicated pulse waveforms. Comparative analysis of the sensitivity and specificity of the proposed indices was carried out in a sample of 45 volunteers of different ages and states of arterial health. It was found that the proposed spectral index has higher sensitivity (89%) and specificity (86%) compared to the time-domain indices.
