Background— Specific noninvasive signal processing was applied to identify drivers in distinct
categories of persistent atrial fibrillation (AF). Methods and Results— In 103 consecutive …

Background— Catheter ablation of ventricular tachycardia (VT) is effective and particularly
useful in patients with frequent defibrillator interventions. Various substrate modification …

Background— This study aimed to determine 5-year efficacy of catheter ablation for persistent
atrial fibrillation (AF) using AF termination as a procedural end point. Methods and Results…

Noninvasive Panoramic Mapping of Human Atrial Fibrillation Mechanisms Introduction
Recent developments in body surface mapping and computer processing have allowed …

The mechanisms responsible for perpetuation of human persistent atrial fibrillation (AF) are
controversial and probably vary between individuals. A wide spectrum of mechanisms have …

BACKGROUND: Left atrial appendage (LAA) is implicated in maintenance of atrial fibrillation
(AF) and atrial tachycardia (AT) associated with persistent AF (PsAF) ablation, although …

Objectives : This study sought to evaluate the relationship between fibrosis imaged by
delayed-enhancement (DE) magnetic resonance imaging (MRI) and atrial electrograms (Egms) in …

Objectives : This study prospectively evaluated the role of a novel 3-dimensional, noninvasive,
beat-by-beat mapping system, Electrocardiographic Mapping (ECM), in facilitating the …

In susceptible individuals, inhalation of Aspergillus spores can affect the respiratory tract in
many ways. These spores get trapped in the viscid sputum of asthmatic subjects which …

Objectives : This study sought to investigate whether noninvasive electrocardiographic
activation mapping is a useful method for predicting response to cardiac resynchronization …
