This study presents an automatic diagnostic method for the discrimination between persistent and long-standing atrial fibrillation (AF) based on the surface electrocardiogram (ECG). Standard 12-lead ECG recordings were acquired in 53 patients with either p ...

Physical activity of moderately impaired elderly stroke patients during rehabilitation

Kamiar Aminian

In older adults, physical activity (PA) is promoted for public health preventive effort. It is also a major target in the rehabilitation process. Existing assessment tools in the clinical routine do not include any aspects of PA or participation and are of ...

We propose a new method for ventricular cancellation and atrial modelling in the ECG of patients suffering from atrial fibrillation. Our method is based on dictionary learning. It extends both the average beat subtraction and the sparse source separation a ...

Clinical standard 12-lead ECG recordings over 5 minutes on patients in atrial fibrillation or in atrial flutter were analyzed. After suppression of the signal components related to ventricular activity, the amplitude spectra of all leads were inspected. Th ...

Adaptive Frequency Tracking on the ECG Used to Predict the Success of Electrical Cardioversion of Atrial Fibrillation

Jean-Marc Vesin, Mathieu Lemay, Yann Prudat, Frank Grégoire Jean de Morsier

One of the rhythm control strategies in atrial fibrillation management consists in the application of a brief single electrical shock to the atria. This electrical cardioversion does not always succeed, and the long-term success of this therapy is not suff ...

Data processing techniques for the characterization of atrial fibrillation

Mathieu Lemay

Atrial fibrillation is the most common sustained cardiac rhythm disturbance, increasing in prevalence with age. During the past 20 years, there has been a 66% increase in hospital admissions related to atrial fibrillation. Neither the natural history of at ...

Vectorcardiographic lead systems for the characterization of atrial fibrillation

Vincent Jacquemet, Zenichi Ihara

Objective: To design a VCG lead system dedicated to the analysis of atrial fibrillation. Methods: Body surface potentials during atrial fibrillation were simulated by using a biophysical model of the human atria and thorax. The XYZ components of the equiva ...

Analysing the potential of Reveal for monitoring cardiac potentials

Aims The implantable loop recorder (ILR) continuously monitors the heart’s electric activity by means of a subcutaneous bipolar electrogram (Elg). Currently, the relationship between the Elg and the surface electrocardiogram (ECG) has been poorly documente ...

Design and performance of lead systems for the analysis of atrial signal components in the ECG

Zenichi Ihara

For over a century, electrocardiology has been observing human cardiac activity through recordings of electrocardiograms (ECG). The potential differences derived from the nine electrodes of the standard 12-lead ECG, placed at their designated positions, ar ...

Ventricular and Atrial Activity Estimation Through Sparse ECG Signal Decompositions

Pierre Vandergheynst, 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 ...
