Adaptive Filtering of the Arterial Wall: Frequency Response and Dynamical Parameters: Clinical Evaluation.

Adaptive identification systems focus on dynamical approaches based on the observed data from an experiment and/or clinical data. These systems establish a relationship between an input (arterial or vein instantaneous pressure) and an output (instantaneous arterial or vein diameter). Several dynamics relationships and applications can be established because of this adaptive identification as an arterial dynamic range (frequency response), biomechanical behavior of cryopreserved arteries, regional differences in veins as artery substitution, role of vascular smooth muscle in human hypertension and time invariance in the biomechanics of wall arteries. The aim of this review is to summarize some of those relevant results obtained from adaptive filter identification in cardiovascular dynamics research and clinical evaluation.
