Influence of heart motion on cardiac output estimation by means of electrical impedance tomography: a case study

Jean-Philippe Thiran, Mathieu Lemay, Fabian Braun, Martin Proença, Michaël Rapin

Electrical impedance tomography (EIT) is a non-invasive imaging technique that can measure cardiac-related intra-thoracic impedance changes. EIT-based cardiac output estimation relies on the assumption that the amplitude of the impedance change in the vent ...

Estimation of Blood Pressure and Pulse Transit Time Using Your Smartphone

David Atienza Alonso, Francisco Javier Rincon Vallejos, Srinivasan Murali, Alair Dias Junior

It is widely recognized today that there is an alarming rise of lifestyle-induced chronic diseases (e.g., type II diabetes) in our society. Therefore, a strong need exists for cost-effective and non-invasive devices that can measure blood pressure (BP) to ...

Markers for risk to develop atrial fibrillation based on a new electrocardiographic tool

Atrial fibrillation (AF) is the most important trigger for heart failure and stroke. Reliable methods for predicting AF are lacking and ECG analysis could improve this process. P-wave characteristics in the ECG are an important source of information in the ...

Sensing ECG signals with variable pulse width finite rate of innovation

Gilles Baechler

Mobile health is gradually taking more importance in our society and the need of new power efficient devices acquiring biosignals for long periods of time is becoming substantial. In this thesis, we study the power reduction we could achieve on ECG sensing ...

P-wave Indices to Detect Susceptibility to Atrial Fibrillation

Jean-Marc Vesin, Andréa Buttu

The aim of this work is to present different markers resulting from the analysis of a single ECG lead recorded during sinus rhythm. To this purpose, the ECGs from three populations were compared: healthy subjects, patients subject to paroxysmal AF selected ...

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

Jean-Marc Vesin, Lam Dang, Lukas Kappenberger

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 ...

Melanocyte-like cells in the heart and pulmonary veins contribute to atrial arrhythmia triggers

Friedrich Beermann, Fang Liu

Atrial fibrillation is the most common clinical cardiac arrhythmia. It is often initiated by ectopic beats arising from the pulmonary veins and atrium, but the source and mechanism of these beats remains unclear. The melanin synthesis enzyme dopachrome tau ...

Activity Level of an Atrial Ectopic Focus Observed Through the Equivalent Dipole: a Biophysical Model

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene, Vincent Jacquemet

Quantifying the role of atrial ectopic foci in the initiation and the maintenance of atrial fibrillation (AF) is a relevant clinical problem. This study aims at assessing the relation between the activity level of an ectopic focus and the complexity of the ...
