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.

Ion channel dysfunction in humans leads to impairment of the excitable processes necessary for the normal function of several tissues, such as muscle and brain. It follows that an increasing number of human diseases have been associated with malfunctioning ion channels, many of which have a genetic component. This volume of Advances in Genetics presents a broad and comprehensive overview of the inherited channelopathies in humans, including clinical, genetic and molecular aspects of these conditions. Keeping true to the scope of the serial, novel genomic and modeling research approaches and a review of potential therapeutic approaches for each of these conditions are also incorporated.

Brugada Phenocopy: The Art of Recognizing the Brugada ECG Pattern details all aspects associated with alternative diagnosis to Brugada Syndrome (BrS). Coverage includes how to identify the proper ECG pattern, what to do to investigate for BrP, and how to avoid misinterpretations and the use of unnecessary and expensive treatments. Chapters are written by experienced professionals, many of whom are colleagues that initially described this condition. This easy to use volume is a must have reference for researchers of cardiology, cardiologists, electrocardiologists, internists, emergency care doctors and students, residents and fellows. - Assists in the proper recognition of the Brugada ECG patterns and how to distinguish true BrS from other conditions with identical ECG - Expands understanding on how to properly recognize the ECG of Brugada patterns - Contains access to a companion website with video to enhance understanding of proper measurement of the beta angle (Chevallier) and the base of the triangle (Serra)

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.

This engaging book covers a multitude of topics related to heart rhythm disorders (HRDs) and uniquely familiarizes readers with the development of treatment modalities over the past several decades, including the evolution of anti-arrhythmic drugs, pacemakers, defibrillators, and catheter ablation. Organized in ten sections, this title serves as both an archival and a contemporary resource for clinicians. The first section describes the discovery of the circulatory system by William Harvey in 1628 and outlines the development and understanding of HRD since the advent of intra-cardiac electrophysiology. Subsequent sections discuss the historical evolution of abnormal heart rhythms, such as supra and ventricular rhythms and sudden cardiac death, their treatment with drugs, surgery, pacemakers, implantable defibrillators and catheter ablation. Section nine offers a fascinating narration of the clinical evolution of overcoming heart attacks and its impact on HRDs. The final section explores potential new frontiers in HRD and the factors that may contribute to the prospective rise of cardiovascular diseases. A ground-breaking and invaluable addition to the clinical literature, Heart Rhythm Disorders: History, Mechanisms and Management Perspectives details the pervasive nature of cardiovascular diseases in human history, their ramifications, and their projected effects on at-risk demographic populations and human health in general.
