ECG-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 ...

Extraction of QRS fiducial points from the ECG using adaptive mathematical morphology

Jean-Marc Vesin, Sasan Yazdani

QRS complex detection in the electrocardiogram (ECG) has been extensively investigated over the last two decades. Still, some issues remain pending due to the diversity of QRS complex shapes and various perturbations, notably baseline drift. This is especi ...

Improving emotional face perception in autism with diuretic bumetanide: A proof-of-concept behavioral and functional brain imaging pilot study

Nouchine Hadjikhani, Loyse Hippolyte, Ophélie Rogier, Torsten Ruest

Clinical observations have shown that GABA-acting benzodiazepines exert paradoxical excitatory effects in autism, suggesting elevated intracellular chloride (Cl-)(i) and excitatory action of GABA. In a previous double-blind randomized study, we have shown ...

An Oral Formulation of Angiotensin-(1-7) Reverses Corpus Cavernosum Damages Induced by Hypercholesterolemia

Nikolaos Stergiopoulos, Fabiana Pereira Da Costa Fraga, Danielle Gomes Passos Silva

Introduction The renin angiotensin system plays a crucial role in erectile function. It has been shown that elevated angiotensin-II levels contribute to the development of erectile dysfunction (ED). Oppositely, angiotensin-(1-7) (Ang-[1-7]) mediates penile ...

Design of Energy Efficient and Dependable Health Monitoring Systems under Unreliable Nanometer Technologies

David Atienza Alonso, Andreas Peter Burg, Georgios Karakonstantis, Mohamed Mostafa Sabry Aly

In this paper we investigate the impact of potential hardware misbehavior induced by reliability issues and scaled voltages in wireless body sensor network (WBSN) nodes. Our study reveals the inherent resilience of popular algorithms in cardiac monitoring ...

The Role of Atrial Modeling in the Development of ECG Processing Tools

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene, Laurent Renaud Uldry, Vincent Jacquemet, Lukas Kappenberger

The standard ECG remains the most common non-invasive tool for assessing atrial fibrillation. Specific signal processing techniques have been developed to improve the diagnosis. However, validation of such tools is challenging and comprehensive invasive da ...
