Assessment of AF capture during antitachycardia pacing using largest Lyapunov exponent estimation. Insights from a biophysical model

The present study investigates the potential of the Largest Lyapunov Exponent (LLE) for the quantification of AF complexity as a marker of antitachycardia pacing (ATP) effectiveness in a biophysical model of the human atria. From ongoing simulated atrial f ...

Influence of atrial substrate on local capture induced by rapid pacing of atrial fibrillation

Jean-Marc Vesin, Vincent Jacquemet, Alexandru Rusu

Preliminary studies showed that the septum area was the only location allowing local capture of both the atria during rapid pacing of atrial fibrillation (AF) from a single site. The present model-based study investigated the influence of atrial substrate ...

Correlation Dimension as a Measure of the Atrial Fibrillation Capture during Atrial Septal Pacing

Jean-Marc Vesin, Adrian Luca

In the present model-based study, the correlation dimension (D2) was used as a measure of the effectiveness of atrial septal pacing during atrial fibrillation (AF). From ongoing simulated atrial fibrillation, instantaneous transmembrane potential maps were ...

Intermittent Atrial Tachycardia Promotes Repolarization Alternans and Conduction Slowing During Rapid Rates, and Increases Susceptibility to Atrial Fibrillation in a Free-Behaving Sheep Model

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Repolarization Alternans and Atrial Remodeling Introduction Paroxysmal atrial fibrillation (AF) may be triggered by intermittent atrial tachycardia, and ultimately lead to persistent AF. However, the mechanisms by which intermittent atrial tachycardia prom ...

Novel ECG and Intracardiac Electrograms Signal Processing Schemes for Predicting the Outcome of Atrial Fibrillation Catheter Ablation

Andréa Buttu

Atrial fibrillation (AF) is the most common encountered cardiac rhythm disorder (arrhythmia) in clinical practice. It is responsible for about one third of arrhythmia-related hospitalizations. This arrhythmia, which increases in prevalence with age, leads ...

Impact of Bachmann’s Bundle on Rapid Pacing of Atrial Fibrillation from the Septum Area

Rapid pacing of atrial fibrillation (AF) can induce local capture of the atrial tissue and preliminary studies showed that the septum area was the only location allowing simultaneous capture of both atria from a single site. The present model-based study i ...

High bi-atrial organization in patients with long-standing persistent atrial fibrillation terminated within the left atrium

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot

Sustained atrial fibrillation (AF) is maintained by sites displaying high dominant frequency (DF). In patients (pts) with long-standing persistent AF (LS-pAF), their spatial distribution and the presence of a left-to-right atrial DF gradient remain poorly ...

Adaptive frequency tracking of the baseline ECG identifies the site of atrial fibrillation termination by catheter ablation

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

Multiple organization indices have been used to predict the outcome of stepwise catheter ablation in long-standing persistent atrial fibrillation (AF), however with limited success. Our study aims at developing innovative organization indices from baseline ...

High pre-ablation ECG organization in long-standing persistent atrial fibrillation terminated within the left atrium

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

The outcome of stepwise catheter ablation (step-CA) for patients (pts) with long-standing atrial fibrillation (LS-pAF) is poorly predicted by classical organization indices (OI). Our study aims at developing new indices from pre-ablation ECG in order to id ...

Measures of Right Atrial Organization as a Mean to Select Candidates for Sinus Rhythm Restoration by Catheter Ablation

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot

Stepwise catheter ablation (step-CA) can terminate long-standing persistent atrial fibrillation (LS-pAF) within the left atrium (LA) or may require additional right atrial (RA) ablation. Intracardiac organization indices such as AF cycle length (AFCL) have ...
