Computational simulations of cardiac electrophysiology provide detailed information on the
depolarization phenomena at different spatial and temporal scales. With the development of …

The arrhythmogenesis of atrial fibrillation is associated with the presence of fibrotic atrial
tissue. Not only fibrosis but also physiological anatomical variability of the atria and the …

Aims Electro-anatomical voltage, conduction velocity (CV) mapping, and late gadolinium
enhancement (LGE) magnetic resonance imaging (MRI) have been correlated with atrial …

In patients with atrial fibrillation, intracardiac electrogram signal amplitude is known to
decrease with increased structural tissue remodeling, referred to as fibrosis. In addition to …

Introduction: The omnipolar electrogram method was recently proposed to try to generate
orientation-independent electrograms. It estimates the electric field from the bipolar …

Background: Ultra-high-density mapping systems allow more precise measurement of the
heart chambers at corresponding conduction velocities (CVs) and voltage amplitudes (VAs) …

Background Optimal method for voltage assessment in AF remains unclear. Objectives This
study evaluated different methods for assessing atrial voltage and their accuracy in …

The autonomic nervous system (ANS) plays an essential role in the generation and
maintenance of cardiac arrhythmias. The cardiac ANS can be divided into its extrinsic and …

Introduction Epicardial adipose tissue (EAT) exacerbates both electrical and structural
remodeling in obese atrial fibrillation (AF) patients, but the impacts of EAT on atrial …

Background Low-voltage-substrate (LVS)-guided ablation for persistent atrial fibrillation (AF)
has been described either in sinus rhythm (SR) or AF. Prolonged fractionated potentials …
