The non invasive analysis of atrial fibrillation (AF) arrhythmia represents a challenge nowadays. The fibrillatory pattern of AF, known as f-wave, is partially masked by the ventricular activity of the heartbeat in the surface electrocardiogram (ECG). Classical techniques aiming to extract the f-wave are based on average beat subtraction (ABS)...

Atrial fibrillation (AF) is a sustained arrhythmia whose mechanisms are still largely unknown. A recent patient-tailored AF ablation therapy is based on the use of a multipolar mapping catheter called PentaRay. This new protocol targets areas of spatiotemporal dispersion (STD) in the atria as potentialAF drivers. However, interventional...

A recent patient-tailored ablation protocol to treat atrial fibrillation consists in identifying ablation sites based on their spatiotemporal dispersion (STD). STD represents a delay of the cardiac activation observed in intracardiac electrograms (EGMs) across contiguous leads. This work aims at automatically identifying ablation sites by...

Automatic identification of different arrhythmias helps cardiologists better diagnose patients with cardiovascular diseases. Deep learning algorithms are used for the classification of multichannel ECG signals into different heart rhythms. The study dataset includes a cohort of 43101 12-lead ECG recordings with various lengths. Two options are...

Atrial Fibrillation (AF) is the most widespread sustained arrhythmia in clinical practice. A recent personalized AF therapy consists in ablating areas displaying spatiotemporal dispersion (STD) electrograms (EGM) with the use of catheters. Interventional cardiologists use a multipolar mapping catheter called PentaRay to identify visually atrial...

Catheter ablation is increasingly used to treat atrial fibrillation (AF), the most common sustained cardiac arrhythmia encountered in clinical practice. A recent breakthrough finding in AF ablation consists in identifying ablation sites based on their spatiotemporal dispersion (STD). STD stands for a delay of the cardiac activation observed in...
