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, Etienne Pruvot, Florian Jousset

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 ...

Severe and uniform bi-atrial remodeling measured by dominant frequency analysis in persistent atrial fibrillation unresponsive to ablation

Jean-Marc Vesin, Etienne Pruvot, Andréa Buttu, Adrian Luca

Background High values of ECG and intracardiac dominant frequency (DF) are indicative of significant atrial remodeling in persistent atrial fibrillation (peAF). We hypothesized that patients with peAF unresponsive to ablation display higher ECG and intraca ...

Prediction of plasma volume and total hemoglobin mass with machine learning

Jean-Marc Vesin

Hemoglobin concentration ([Hb]) is used for the clinical diagnosis of anemia, and in sports as a marker of blood doping. [Hb] is however subject to significant variations mainly due to shifts in plasma volume (PV). This study proposes a newly developed mod ...

Implicit Affective Profiling of Subjects based on Physiological Data Coupling

Touradj Ebrahimi, Jean-Marc Vesin, Eleni Kroupi

Evidence from neuroscience and psychology supports the idea that synchronization among various sub-components of the organism is the key-point to emotional processes. This study investigates the way signals from the central nervous system interact with sig ...

Optimizing Local Capture of Atrial Fibrillation by Rapid Pacing: Study of the Influence of Tissue Dynamics

Jean-Marc Vesin, Vincent Jacquemet, Lukas Kappenberger, Laurent Renaud Uldry

While successful termination by pacing of organized atrial tachycardias has been observed in patients, rapid pacing of AF can induce a local capture of the atrial tissue but in general no termination. The purpose of this study was to perform a systematic e ...

A Non-linear Filter to Detect Atrial Activation from Intracardiac Electrograms

Jean-Marc Vesin, Etienne Pruvot, Sasan Yazdani, Andréa Buttu

Atrial activation (AA) detection during atrial fibrillation (AF) can be considered as a first step in estimating AF characteristics such as the AF cycle length. The detection of AA from intracardiac electrograms (EGM) remains challenging due to the constan ...

A Novel Measure of Instantaneous Baroreflex Sensitivity

Jean-Marc Vesin, Sasan Yazdani, Miljan Petrovic

Various time- and frequency-based approaches have been proposed to measure baroreflex sensitivity. All these methods are block-based ones. This study proposes a novel instantaneous measure of baroreflex sensitivity that enables the investigation of frequen ...

Novel spatiotemporal processing tools for body-surface potential map signals for the prediction of catheter ablation outcome in persistent atrial fibrillation

Jean-Marc Vesin, Etienne Pruvot, Adrian Luca

Background: Signal processing tools are required to efficiently analyze data collected in body-surface-potential map (BSPM) recordings. A limited number of such tools exist for studying persistent atrial fibrillation (persAF). We propose two novel, spatiot ...

Mechano-electrical contribution of ventricular contractions to the complexity of atrial fibrillation electrograms

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot, Sarah Volorio

Purpose: Intracardiac organization indices (OI) have been used to track the efficiency of stepwise radiofrequency catheter ablation (step-CA) of persistent atrial fibrillation (pers-AF). A better understanding of the components and complexity of AF electro ...

False arrhythmia alarms reduction in the intensive care unit: a multimodal approach

Jean-Marc Vesin, Sasan Yazdani, Sibylle Fallet

The purpose of this study was to develop algorithms to lower the incidence of false arrhythmia alarms in the ICU using information from independent sources, namely electrocardiogram (ECG), arterial blood pressure (ABP) and photoplethysmogram (PPG). Our app ...

Susceptibility to Paroxysmal Atrial Fibrillation: A Study using Sinus Rhythm P Wave Parameters

Jean-Marc Vesin, Lukas Kappenberger, Lam Dang

Early recognition of patients at high risk for atrial fibrillation may help to minimize potential health risks. The detection of susceptibility to develop atrial fibrillation is thus a real clinical challenge. Whereas many studies have used the signal-aver ...

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 ...

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 ...
