Non-invasive model-based estimation of the sinus node dynamic properties from spontaneous cardiovascular variability series
A non-invasive model-based approach to the estimation of sinus node dynamic properties is proposed. The model exploits the spontaneous beat-to-beat variability of heart period and systolic arterial pressure an...

Article
Analysis of cardiac left-ventricular volume based on time war** averaging
The cardiac left-ventricular (LV) volume signal, obtained by acoustic quantification, is affected by noise and respiratory modulation, resulting in a large beat-to-beat variability that affects the computation...

Information domain analysis of cardiovascular variability signals: Evaluation of regularity, synchronisation and co-ordination
A unifying general approach to measure regularity, synchronisation and co-ordination is proposed. This approach is based on conditional entropy and is specifically designed to deal with a small amount of data ...

Article
Quantifying electrocardiogram RT-RR variability interactions
A dynamic linear parametric model is designed to quantify the dependence of ventricular repolarisation duration variability on heart period changes and other immeasurable factors. The model analyses the beat-t...

Model for the assessment of heart period and arterial pressure variability interactions and of respiration influences
A model which assesses the closed-loop interaction between heart period (HP) and arterial pressure (AP) variabilities and the influence of respiration on both is applied to evaluate the sources of low frequenc...

Spectral Analysis of Cardiovascular Variables as a Tool to Quantify Neural Cardiovascular Control in the Laboratory and Real Life Conditions
The neural control of the circulation depends upon a continuous interaction between opposite, i.e. negative and positive, feed-back mechanisms, mediated respectively by vagal/baroreceptive and sympathetic circ...

Power Spectral Analysis of Heart Rate and Arterial Pressure Variabilities as an Experimental and Clinical Tool
The possibility recently offered by computer techniques for quantifying the small spontaneous beat-by-beat oscillations characterizing the cardiovascular variables and in particular the electrocardiographic R-...
