Blind 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 کاملCharacterization 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 کاملDiagnosis of atrial fibrillation using electrograms from chronic leads: evaluation of computer algorithms.
This study compares the performance of three detection algorithms for the recognition of atrial fibrillation in chronic pacing leads. Multiple serial recordings were obtained of wideband and filtered electrograms from chronic atrial and ventricular leads in dogs for a period up to 55 days following implantation. Each dog was recorded in sinus rhythm and induced atrial fibrillation. Four days we...
متن کاملAn Algorithm for the Detection and Classification of Atrial Fibrillation from Intra-atrial Electrograms
Reliable detection of atrial fibrillation from intra-atrial signals is a central task in the development of implantable atrial defibrillators. Atrial rate (AR) and the amplitude probability density function (APDF) are normally used as parameters for discriminating between normal sinus rhythm (NSR) and atrial fibrillation (AF). We hereby propose a new peak-detection scheme based on threshold cro...
متن کاملNonlinear analysis of epicardial atrial electrograms of electrically induced atrial fibrillation in man.
INTRODUCTION We applied methods from the theory of nonlinear dynamics to characterize unipolar epicardial right atrial electrograms of electrically induced atrial fibrillation (AF) in man. METHODS AND RESULTS Electrograms were selected from a high-density mapping study, which confirmed the existence of at least 3 different types of induced AF (types I, II, and III) in patients undergoing open...
