Application of the fastest route algorithm in the interactive simulation of the effect of local ischemia on the ECG

A method is described to determine the effect on the ECG of a reduced propagation velocity within an ischemic zone. The method was designed to change the activation sequence throughout the ventricles interactively, i.e. with a response time in the order of ...

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 ...

Data processing techniques for the characterization of atrial fibrillation

Mathieu Lemay

Atrial fibrillation is the most common sustained cardiac rhythm disturbance, increasing in prevalence with age. During the past 20 years, there has been a 66% increase in hospital admissions related to atrial fibrillation. Neither the natural history of at ...

Propagation velocity kinetics and repolarization alternans in a free-behaving sheep model of pacing-induced atrial fibrillation

Jean-Marc Vesin, Yann Prudat, Florian Jousset, Etienne Pruvot

Aims: Experimental models have reported conflicting results regarding the role of dispersion of repolarization in promoting atrial fibrillation (AF). Repolarization alternans, a beat-to-beat alternation in action potential duration, enhances dispersion of ...

Compression of ECG as a Signal with Finite Rate of Innovation

Martin Vetterli, Thierry Blu, Yan Hao

Compression of ECG (electrocardiogram) as a signal with finite rate of innovation (FRI) is proposed in this paper. By modelling the ECG signal as the sum of bandlimited and nonuniform linear spline which contains finite rate of innovation (FRI), sampling t ...

A biophysical model of atrial fibrillation and electrograms

Vincent Jacquemet

Atrial arrhythmias are the most frequent rhythm disorders in humans and often lead to severe complications such as heart failure and stroke. While different mapping techniques have provided significant information on the electrophysiological processes asso ...
