Ability of magnetocardiography to detect regional dominant frequencies of atrial fibrillation.
BACKGROUND Lead V1 on electrocardiography (ECG) can detect the dominant frequency (DF) of atrial fibrillation (AF) in the right atrium (RA). Paroxysmal AF is characterized by a frequency gradient from the left atrium (LA) to the right atrium (RA). We examined the ability of magnetocardiography (MCG) to detect regional DFs in both the atria. METHODS Study subjects comprised 18 consecutive pati...
متن کاملReview of Dominant Frequency Analysis in Atrial Fibrillation.
Significant advancements have been made in the technology and approach to catheter ablation of atrial fibrillation (AF). Pulmonary vein isolation has emerged as the dominant strategy in this procedure and has fueled innovations in catheter design as well as various mapping and navigation systems. Mapping and targeting of complex fractionated atrial electrograms has also emerged as an additional...
متن کاملLeft-to-right gradient of atrial frequencies during acute atrial fibrillation in the isolated sheep heart.
BACKGROUND Recent studies demonstrated spatiotemporal organization in atrial fibrillation (AF). We hypothesized that waves emanating from sources in the left atrium (LA) undergo fragmentation, resulting in left-to-right frequency gradient. Our objective was to characterize impulse propagation across Bachmann's bundle (BB) and the inferoposterior pathway (IPP) during AF. METHODS AND RESULTS In...
متن کاملGranger Causality and Jensen-Shannon Divergence to Determine Dominant Atrial Area in Atrial Fibrillation
Atrial fibrillation (AF) is already the most commonly occurring arrhythmia. Catheter pulmonary vein ablation has emerged as a treatment that is able to make the arrhythmia disappear; nevertheless, recurrence to arrhythmia is very frequent. In this study, it is proposed to perform an analysis of the electrical signals recorded from bipolar catheters at three locations, pulmonary veins and the ri...
متن کاملProtective effects of simvastatin on atrioventricular node during simulated experimental atrial fibrillation in vitro
Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...
