Characterization of Electrograms from Multipolar Diagnostic Catheters during Atrial Fibrillation
Atrial fibrillation (AF) is the most common arrhythmia in USA with more than 2.3 million people affected annually. Catheter ablation procedure is a method for treatment of AF, which involves 3D electroanatomic mapping of the patient's left atrium (LA) by maneuvering a conventional multipolar diagnostic catheter (MPDC) along the LA endocardial surface after which pulmonary vein (PV) isolation is...
متن کاملTime- and frequency-domain characteristics of atrial electrograms during sinus rhythm and atrial fibrillation.
BACKGROUND Complex fractionated atrial electrograms (CFAE) have been considered to be helpful during catheter ablation of atrial fibrillation (AF). The purpose of this study was to analyze the characteristics of CFAEs recorded during sinus rhythm (SR) and AF, and to determine their relationship to perpetuation of AF and clinical outcome. METHODS AND RESULTS Antral pulmonary vein isolation (AP...
متن کاملVisualization of Intracardiac Atrial Electrograms of Patients with Atrial Fibrillation using Spectral Analysis
Atrial fibrillation is the most common cardiac arrhythmia, and it is associated with increased risk of stroke, heart failure and mortality. In this work we describe spectral analysis techniques that are being used in conjunction with visualization algorithms to help guide catheter ablation procedures that aim at treating patients with the arrhythmia.
متن کاملBlind analysis of atrial fibrillation electrograms: A sparsity-aware formulation
Abstract. The problem of blind sparse analysis of electrogram (EGM) signals under atrial fibrillation (AF) conditions is considered in this paper. A mathematical model for the observed signals that takes into account the multiple foci typically appearing inside the heart during AF is firstly introduced. Then, a reconstruction model based on a fixed dictionary is developed and several alternativ...
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...
