We aim to provide a critical appraisal of basic concepts underlying signal recording and
processing technologies applied for (i) atrial fibrillation (AF) mapping to unravel AF …

Electrocardiographic imaging (ECGI) reconstructs the electrical activity of the heart from a
dense array of body-surface electrocardiograms and a patient-specific heart-torso geometry …

Recent advances in our understanding of the mechanisms underlying atrial fibrillation (AF)
have further underscored the complex pathophysiological basis of the arrhythmia. It has …

AF is a heterogeneous rhythm disorder that is related to a wide spectrum of etiologies and
has broad clinical presentations. Mechanisms underlying AF are complex and remain …

Objectives: This study sought to assess the relationship between fibrosis and re-entrant
activity in persistent atrial fibrillation (AF). Background: The mechanisms involved in …

Recent studies strongly suggest that the majority of atrial fibrillation (AF) patients with
diagnosed or subclinical cardiac diseases have established or even pre-existing fibrotic …

Abstract Treatment of atrial fibrillation (AF), the most common arrhythmia in clinical practice,
remains challenging. Improved understanding of underlying mechanisms is needed to …

Objectives: This study sought to improve atrial fibrillation (AF) driver identification by
integrating clinical multielectrode mapping with driver fingerprints defined by high-resolution …

Background: Atrial fibrillation (AF) can be maintained by localized intramural reentrant
drivers. However, AF driver detection by clinical surface-only multielectrode mapping (MEM) …

Background: Phase mapping has become a broadly used technique to identify atrial
reentrant circuits for ablative therapy guidance. This work studies the phase mapping …
