Research output: Contribution to journalArticle


An adaptive scheme for the weighted-least-square (WLS) is proposed. Algorithm performance in individuating the tracking the modifications of the cardiac autonomic control is illustrated. To make data interpretation easier, the time-frequency distributions are displayed as spectrograms. Additionally, the signal speed variation is used to draw the attention of the physician to transient episodes.
