Automated Assessment to Predict Lethal Arrhythmias in Brugada Syndrome: Significance of R' in Lead III

Journal of Arrhythmia
Background Previous investigations of predictors of sudden cardiac arrest (SCA) in Brugada syndrome (BrS) have been conducted using manual electrocardiogram (ECG) measurement, which lacks objectivity.

Data_Sheet_1_Epicardial Fibrosis Explains Increased Endo–Epicardial Dissociation and Epicardial Breakthroughs in Human Atrial Fibrillation.pdf

, 2020
BackgroundAtrial fibrillation (AF) is accompanied by progressive epicardial fibrosis, dissociation of electrical activity between the epicardial layer and the endocardial bundle network, and transmural conduction (breakthroughs).

Signal-averaged electrocardiography as a noninvasive tool for evaluating the ventricular substrate in patients with nonischemic cardiomyopathy: reassessment of an old tool

Frontiers in Cardiovascular Medicine
IntroductionSignal-averaged electrocardiography (SAECG) provides diagnostic and prognostic information regarding cardiac diseases. However, its value in other nonischemic cardiomyopathies (NICMs) remains unclear.

Mapping of epicardial activation in a rabbit model of chronic myocardial infarction: Response to atrial, endocardial, and epicardial pacing

, 2007
Introduction: This study examines the consequences of a large transmural apical infarct on the epicardial electrical activity in isolated rabbit hearts. Methods and Results: Hearts were isolated 8 weeks after coronary artery ligation. Membrane voltage

Atrial fibrillation: A never ending story?

Clinical Case Reports, 2019
Atrial fibrillation (AF) often recurs after ablative therapy. In our patient, intraoperative epicardial mapping during therapy‐ resistant AF revealed highly dissociated atrial conduction patterns and that long lines of conduction block throughout the ...

Side-Viewing Near-Infrared Spectroscopy for Depth-Sensitive Mapping of Ventricular Epicardial Ablation Lesions

A side-viewing, multi-detector NIRS probe enables depth-sensitive mapping of epicardial radiofrequency ablation lesions. In 11 porcine hearts, SDS-specific spectral indices identified lesion regions and showed depth-dependent signatures across 1-6 mm ...

Clinical utility of multielectrode contact mapping for scar-related ventricular tachycardia ablation: A prospective single-center experience

Journal of Arrhythmia, 2014
Background: As with the use of circular catheters for pulmonary vein antral ablation, it may be favorable to use multipolar catheters for substrate mapping of the left ventricle (LV).

Case Report: Epi-endocardial bridges in refractory cavotricuspid isthmus-dependent atrial flutter: technical analysis of epi-endocardial breakthrough

Frontiers in Cardiovascular Medicine
BackgroundTypical isthmus-dependent atrial flutter (AFL) is traditionally treated through radiofrequency (RF) ablation to create a bidirectional conduction block across the cavo-tricuspid isthmus (CTI) in the right atrium.
