Electrocardiographic imaging (ECGI) is a technique to reconstruct non-invasively the
electrical activity on the heart surface from body-surface potential recordings and geometric …

Frequency Trajectory of Atrial Fibrillation Introduction The role of substrates in the
maintenance of persistent atrial fibrillation (persAF) remains poorly understood. The use of …

Purpose Recent investigations failed to reproduce the positive rotor-guided ablation
outcomes shown by initial studies for treating persistent atrial fibrillation (persAF). Phase …

Abstract Background and Objective Optimal targets for persistent atrial fibrillation (persAF)
ablation are still debated. Atrial regions hosting high dominant frequency (HDF) are believed …

Electroanatomical mapping (EAM) systems are commonly used in clinical practice for
guiding catheter ablation treatments of common arrhythmias. In focal tachycardias, the …

Background and objective Cardiac arrhythmias are disorders in terms of speed or rhythm in
the heart's electrical system. Atrial fibrillation (AFib) is the most common sustained …

Background Areas with high frequency activity within the atrium are thought to be 'drivers' of
the rhythm in patients with atrial fibrillation (AF) and ablation of these areas seems to be an …

Background Dominant frequency (DF) analysis of atrial electrograms has become an
important method in characterizing atrial fibrillation (AF). As a classic method, Botteron's …

Making a correct diagnosis of the type of arrhythmia is conducive to the prevention and
treatment of heart disease, abnormal heart rhythm may be caused by underlying heart …

Atrial electrograms (EGMs) with high dominant frequency (DF) are believed to represent
atrial substrates with periodic activation responsible for the maintenance of persistent atrial …
