An integrated heart-torso electromechanical model for the simulation of electrophysiological outputs accounting for myocardial deformation
Alfio Quarteroni, Francesco Regazzoni
When generating in-silico clinical electrophysiological outputs, such as electrocardiograms (ECGs) and body surface potential maps (BSPMs), mathematical models have relied on single physics, i.e. of the cardiac electrophysiology (EP), neglecting the role o ...
Elsevier Science Sa2024ECG-Based Indices to Characterize Persistent Atrial Fibrillation Before and During Stepwise Catheter Ablation
Jean-Marc Vesin, Adrian Luca, Etienne Pruvot
Background: Consistently successful patient outcomes following catheter ablation (CA) for treatment of persistent atrial fibrillation (pers-AF) remain elusive. We propose an electrocardiogram (ECG) analysis designed to (1) refine selection of patients most ...
FRONTIERS MEDIA SA2021A Computational Study of the Electrophysiological Substrate in Patients Suffering From Atrial Fibrillation
Alfio Quarteroni, Andrea Manzoni
In the context of cardiac electrophysiology, we propose a novel computational approach to highlight and explain the long-debated mechanisms behind atrial fibrillation (AF) and to reliably numerically predict its induction and sustainment. A key role is pla ...
FRONTIERS MEDIA SA2021Outer loop and isthmus in ventricular tachycardia circuits: Characteristics and implications
Alfio Quarteroni, Andrea Manzoni, Stefano Pagani
BACKGROUND The isthmus of ventricular tachycardia (VT) circuits has been extensively characterized. Few data exist regarding the contribution of the outer loop (OL) to the VT circuit. OBJECTIVE The purpose of this study was to characterize the electrophysi ...
2020Ventricular response regularity in atrial fibrillation and its relationship to successful catheter ablation
Jean-Marc Vesin, Adrian Luca, Etienne Pruvot
Atrial rate is known to modulate ventricular response during atrial fibrillation (AF). The resulting pulse irregularity translates into widely varying inter-beat intervals (IBIs) extracted from recorded surface electrocardiogram (ECG) activity. In AF, the ...
IEEE2020Cortical reactive balance responses to unexpected slippages while walking: a pilot study
Silvestro Micera, Daniela De Venuto
Understanding how the human brain cortex behaves when the dynamical balance is unexpectedly challenged can be useful to enable fall prevention strategies during daily activities. In this respect, we designed and tested a novel methodological approach to ea ...
IEEE2019Can one detect atrial fibrillation using a wrist-type photoplethysmographic device?
Jean-Marc Vesin, Mathieu Lemay, Célestin Leupi, Sibylle Fallet, Etienne Pruvot, Philippe Renevey
This study aims at evaluating the potential of a wrist-type photoplethysmographic (PPG) device to discriminate between atrial fibrillation (AF) and other types of rhythm. Data from 17 patients undergoing catheter ablation of various arrhythmias were proces ...
SPRINGER HEIDELBERG2019Concealed abnormal atrial phenotype in patients with Brugada syndrome and no history of atrial fibrillation
Jean-Marc Vesin, Adrian Luca, Sasan Yazdani, Lukas Kappenberger
Objectives The electrocardiogram (ECG) of patients with BrS in sinus rhythm might reflect intrinsic atrial electrical abnormalities independent from any previous atrial fibrillation (AF). Aim of this study is to investigate the presence of P-wave abnormali ...
Elsevier2018Usefulness of P-Wave Duration and Morphologic Variability to Identify Patients Prone to Paroxysmal Atrial Fibrillation
Jean-Marc Vesin, Adrian Luca, Sasan Yazdani, Lukas Kappenberger
Few data are available on the assessment of P-wave beat-to-beat morphology variability and its ability to identify patients prone to paroxysmal atrial fibrillation (AF) occurrence. Aim of this study was to determine whether electrocardiographic (ECG) param ...
Excerpta Medica Inc-Elsevier Science Inc2017Nonlinear analysis of right atrial electrograms predicts termination of persistent atrial fibrillation within the left atrium by catheter ablation
Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot
The termination of long-standing persistent atrial fibrillation (LS-pAF) can be achieved by stepwise catheter ablation (step-CA) within the left atrium (LA). Our study aims to applying complexity measures derived from nonlinear time series analysis in orde ...
