Adaptive Multiple Frequency Tracking Algorithm: Detection of Stable Atrial Fibrillation Sources from Standard 12-Lead ECG

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene, Vincent Jacquemet

The detection of stable atrial fibrillation (AF) sources remains one of the major challenges in the AF management. In this study, we investigated the feasibility of detecting stable AF sources from (non invasive) data simulated by means of numerical proced ...

Atrial Repolarization Alternans in a Chronic Sheep Model of Pacing-Induced Atrial Fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

In pacing-induced models of atrial fibrillation (AF) that mimic atrial high-frequency foci, the increase in AF susceptibility over time is not paralleled by any increase in dispersion of repolarization (DOR). Measurements of effective refractory periods (E ...

Transfer matrices for deriving the vectorcardiogram: a consumer guide

Zenichi Ihara

In the literature, several different transfer matrices have been presented for deriving the vectorcardiogram (VCG) from the signals observed using a limited set of electrodes. Even when the electrode locations were identical, like 9 of the standard 12-lead ...

Vectorcardiographic lead systems for the characterization of atrial fibrillation

Vincent Jacquemet, Zenichi Ihara

Objective: To design a VCG lead system dedicated to the analysis of atrial fibrillation. Methods: Body surface potentials during atrial fibrillation were simulated by using a biophysical model of the human atria and thorax. The XYZ components of the equiva ...

An investigation into therapies for atrial arrythmias using a biophysical model of the human atria

Lam Dang

The most common type of sustained arrhythmia is atrial fibrillation (AF), affecting about 2% of the general population and 8% to 11% of the elderly, more than 65 years of age. The treatment of atrial arrythmia is still based on empirical considerations and ...
