Ventricular and Atrial Activity Estimation Through Sparse ECG Signal Decompositions

Pierre Vandergheynst, Jean-Marc Vesin, Mathieu Lemay, Lorenzo Granai, Oscar Divorra Escoda

This paper explores a novel approach for ventricular and atrial activities estimation in electrocardiogram (ECG) signals, based on sparse source separation. Sparse decompositions of ECG over signal-adapted multi-component dictionaries can lead to natural s ...

Design and performance of lead systems for the analysis of atrial signal components in the ECG

Zenichi Ihara

For over a century, electrocardiology has been observing human cardiac activity through recordings of electrocardiograms (ECG). The potential differences derived from the nine electrodes of the standard 12-lead ECG, placed at their designated positions, ar ...

A theoretical model of the cellular calcium dynamics and vasomotion in muscular arteries

Michèle Koenigsberger

Muscular arteries possess the ability to control actively their lumen by altering the tone of the smooth muscle cells of the arterial wall, a property which is vital for a large number of the hemodynamical functions of the body. Arterial contraction is due ...
