Book Synopsis Analysis of Atrial Electrograms by : Christopher Schilling
Download or read book Analysis of Atrial Electrograms written by Christopher Schilling and published by KIT Scientific Publishing. This book was released on 2012 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work provides methods to measure and analyze features of atrial electrograms - especially complex fractionated atrial electrograms (CFAEs) - mathematically. Automated classification of CFAEs into clinical meaningful classes is applied and the newly gained electrogram information is visualized on patient specific 3D models of the atria. Clinical applications of the presented methods showed that quantitative measures of CFAEs reveal beneficial information about the underlying arrhythmia.

Book Synopsis Interpretation of Intracardiac Electrograms: The Fundamentals by : David J. Driscoll
Download or read book Interpretation of Intracardiac Electrograms: The Fundamentals written by David J. Driscoll and published by Lippincott Williams & Wilkins. This book was released on 2012-03-29 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Created by experts from the Mayo Clinic, Interpretation of Intracardiac Electrograms: The Fundamentals is a unique, interactive online tool to help trainees, technicians, and clinicians gain a working understanding of basic intracardiac electrophysiologic concepts and tracings. Online examples of tracings combined with dynamic animations illustrate concepts in sinus rhythm, third-degree atrioventricular block, atrioventricular re-entrant tachycardia, ablation procedures, AV nodal re-entrant tachycardia, atrial flutter, atrial fibrillation, and ventricular tachycardia. A self-assessment examination is included so that you may test yourself on the rhythms you have learned, and review those that pose extra difficulty. This unique online teaching tool... • Provides examples of intracardiac electrophysiologic tracings and animation of the electrical wavefronts on a heart diagram • Offers a brief description of each arrhythmia, followed by an interactive version of an intracardiac electrophysiologic tracing • Shows the wavefront as it moves through the heart diagram • Uses color-coded catheters to match the electrophysiologic tracings to which they correspond • Tests your knowledge before and then after using the module with a brief self-assessment exam
Book Synopsis Spectral Analysis of Atrial Fibrillation Electrograms by : Shruti Sharma
Download or read book Spectral Analysis of Atrial Fibrillation Electrograms written by Shruti Sharma and published by . This book was released on 2010 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: VWA has not yet been tested on real fragmented signals due to the inability to detect a ground truth to calculate error. Nevertheless, there is considerable challenge in the analysis of simulated electrogram signals. It improves the correlation coefficient between the ground truth and the frequencies calculated using the current state of the art and the VWA from 0.069 to 0.91 proving to be a more reliable and accurate in capturing the changing frequency of the signal than methods currently used.

Book Synopsis Characterization of Cardiac Electrogram Signals During Atrial Fibrillation by : Prasanth Ganesan
Download or read book Characterization of Cardiac Electrogram Signals During Atrial Fibrillation written by Prasanth Ganesan and published by . This book was released on 2015 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Atrial fibrillation (AF) is the most common cardiac arrhythmia in United States. The most popular treatment for AF is a percutaneous procedure called catheter ablation. Current AF ablation procedures unfortunately have a poor success rate, primarily because the mechanisms involved in AF are incompletely understood even today. Intra-atrial electrograms have previously been shown to provide information on the mechanisms of AF. This thesis focuses on two such mechanisms -- AF-sustaining sites known as sustained rotational activities (RotAs), and atrial tissue with unique electrical properties known as myocardial scars. Catheter ablation procedures today construct the 3D electroanatomic map of the left atrium (LA) by maneuvering a conventional Multipolar Diagnostic Catheter (MPDC) along the LA endocardial surface. These procedures are limited to pulmonary vein isolation and other linear ablation performed on various regions of the left atrium (such as roof and mitral isthmus) where the regions are decided based on the atrial anatomy. However, it remains unclear how to utilize the information provided by the MPDC to analyze and characterize the RotAs and scars. Previous electrogram characterization studies mainly use a single bipole rather than MPDCs to characterize the electrograms based on features such as cycle length or dominant frequency from the time or frequency domain. In this thesis we developed novel techniques for investigating the above mentioned mechanisms using signal analysis, mathematical modeling, numerical simulation and clinical experiments, all utilizing MPDC recordings. First, the variations in the total conduction delay (TCD) from MPDC electrograms as the MPDC moves towards a RotA source was investigated. Second, the maximum peak-to-peak amplitudes of MPDC electrograms recorded during AF and NSR were analyzed. This thesis provides insights into methods of characterization of cardiac electrograms and the findings of this thesis could address the current challenges in AF ablation."--Abstract.

Book Synopsis Signal Analysis of Measurements in Atrial Fibrillation by : Antonio Raul Espinoza
Download or read book Signal Analysis of Measurements in Atrial Fibrillation written by Antonio Raul Espinoza and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atrial fibrillation (AF) is the most common cardiac arrhythmia whose underlying mechanism is still unclear. Catheter ablation is one of the common procedures in its treatment which consists of applying radio-frequency energy to heat and to eradicate tissues that are supposed to be the cause of arrhythmia inside the atrium. However, this procedure has not been always successful and sometimes can be too invasive. Lately there have been different approaches to ablation in order to guide the physician on where to "burn'' in order to have a more effective procedure. The assisted guidance for catheter ablation includes targeting points with complex fractionated atrial electrograms (CFAE) with short cycle length (
Book Synopsis A Multiscale In Silico Study to Characterize the Atrial Electrical Activity of Patients With Atrial Fibrillation : A Translational Study to Guide Ablation Therapy by : Sánchez Arciniegas, Jorge Patricio
Download or read book A Multiscale In Silico Study to Characterize the Atrial Electrical Activity of Patients With Atrial Fibrillation : A Translational Study to Guide Ablation Therapy written by Sánchez Arciniegas, Jorge Patricio and published by KIT Scientific Publishing. This book was released on 2022-05-30 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atrial substrate undergoes electrical and structural remodeling during atrial fibrillation. Detailed multiscale models were used to study the effect of structural remodeling induced at the cellular and tissue levels. Simulated electrograms were used to train a machine-learning algorithm to characterize the substrate. Also, wave propagation direction was tracked from unannotated electrograms. In conclusion, in silico experiments provide insight into electrograms' information of the substrate.
