Download or read book Dispersion of Ventricular Repolarization State ofthe Art written by Bertil Olsson and published by Wiley-Blackwell. This book was released on 2000-10-30 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book is the first to offer an update of contemporary knowledge of the dispersion of ventricular repolarization (DVR), from basic concepts to the clinical application of recently obtained knowledge. World-renowned scientists and clinicians in the frontline of this research area have authored 20 chapters on a range of relevant issues. Growing amounts of recent evidence demonstrate that, in addition to other mechanisms already associated with malignant ventricular arrhythmias, ventricular myocardial cellular repolarization and DVR should be considered as key factors in these arrhythmias, which are a major cause of death in patients with different types of cardiac disease. This understanding has directly impacted clinical practice by creating a platform for development of new treatment concepts. This book will interest Cardiologists, Electrophysiologists, and Basic and Clinical Pharmacologists, and other clinicians interested in learning more about the subject.

Download or read book The Brugada Syndrome written by Charles Antzelevitch and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the cellular basis for sudden death, the BrugadaSyndrome, has largely remained an unknown to modernarrhythmologists and cardiologists, particularly in the absence ofany structural heart disease. Detailed observations of age-groups,especially the young, families and populations where sudden deathfrequently occurs, and improved understanding of its contributoryfactors and mechanisms are, however, showing the way forward. This addition to the Clinical Approaches to Tachyarrhythmias(CATA) Series, written by the investigators who discovered andprobed the Brugada Syndrome, discusses the history, etiology,pathology and clinical manifestations of sudden death. Fromdiagnosis, prognosis, to therapeutic approaches using the latest incathater ablation techniques, electrophysiological surgery, andgenetic appraisal, the work is a testimony to the author'sinvestigation. Using clinical cases in Thailand and Laos, theyfurther unravel the syndrome's molecular mechanisms, studyingrelated syndromes, such as the long-QT syndrome, infant death, andarryhthmogenic right ventricular cardiomyopathy. By being informed of the electrophysiological abnormalities thatcontribute to familial and genetic diseases, physicians,cardiologists and all those who care for patients with cardiacarrhythmias will be better able to identify and treat patients inwhom the Brugada Syndrome may strike next.

Download or read book J Wave Syndromes written by Charles Antzelevitch and published by Springer. This book was released on 2016-06-27 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delineates the state of the art of the diagnosis and treatment of J wave syndromes, as well as where future research needs to be directed. It covers basic science, translational and clinical aspects of these syndromes. The authors are leading experts in their respective fields, who have contributed prominently to the literature concerning these topics. J wave syndromes are one of the hottest topics in cardiology today. Cardiac arrhythmias associated with Brugada syndrome (BrS) or an early repolarization (ER) pattern in the inferior or infero-lateral ECG leads are thought to be mechanistically linked to accentuation of transient outward current (Ito)-mediated J waves. Although BrS and ER syndrome (ERS) differ with respect to magnitude and lead location of abnormal J waves, they are thought to represent a continuous spectrum of phenotypic expression termed J wave syndromes. ERS is divided into three subtypes with the most severe, Type 3, displaying an ER pattern globally in the inferior, lateral and right precordial leads. BrS has been linked to mutations in 19 different genes, whereas ERS has been associated with mutations in 7 different genes. There is a great deal of confusion as to how to properly diagnose and treat the J wave syndromes as well as confusion about the underlying mechanisms. The demonstration of successful epicardial ablation of BrS has provided new therapeutic options for the management of this syndrome for which treatment alternatives are currently very limited, particularly in the case of electrical storms caused by otherwise uncontrollable recurrent VT/VF. An early repolarization pattern is observed in 2-5% of the US population. While it is clear that the vast majority of individuals exhibiting an ER pattern are not at risk for sudden cardiac death, the challenge moving forward is to identify those individuals who truly are at risk and to design safe and effective treatments.

Book excerpt: Electrocardiograms are one of the most widely used methods for evaluating the structure-function relationships of the heart in health and disease. This book is the first of two volumes which reviews recent advancements in electrocardiography. This volume lays the groundwork for understanding the technical aspects of these advancements. The five sections of this volume, Cardiac Anatomy, ECG Technique, ECG Features, Heart Rate Variability and ECG Data Management, provide comprehensive reviews of advancements in the technical and analytical methods for interpreting and evaluating electrocardiograms. This volume is complemented with anatomical diagrams, electrocardiogram recordings, flow diagrams and algorithms which demonstrate the most modern principles of electrocardiography. The chapters which form this volume describe how the technical impediments inherent to instrument-patient interfacing, recording and interpreting variations in electrocardiogram time intervals and morphologies, as well as electrocardiogram data sharing have been effectively overcome. The advent of novel detection, filtering and testing devices are described. Foremost, among these devices are innovative algorithms for automating the evaluation of electrocardiograms.

Download or read book Electrocardiographic Imaging written by Maria S. Guillem and published by Frontiers Media SA. This book was released on 2020-04-17 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical activity in the myocardium coordinates the contraction of the heart, and its knowledge could lead to a better understanding, diagnosis, and treatment of cardiac diseases. This electrical activity generates an electromagnetic field that propagates outside the heart and reaches the human torso surface, where it can be easily measured. Classical electrocardiography aims to interpret the 12-lead electrocardiogram (ECG) to determine cardiac activity and support the diagnosis of cardiac pathologies such as arrhythmias, altered activations, and ischemia. More recently, a higher number of leads is used to reconstruct a more detailed quantitative description of the electrical activity in the heart by solving the so-called inverse problem of electrocardiography. This technique is known as ECG imaging. Today, clinical applications of ECG imaging are showing promising results in guiding a variety of electrophysiological interventions such as catheter ablation of atrial fibrillation and ventricular tachycardia. However, in order to promote the adoption of ECG imaging in the routine clinical practice, further research is required regarding more accurate mathematical methods, further scientific validation under different preclinical scenarios and a more extensive clinical validation
