J Wave Syndromes by Charles Antzelevitch,Gan-Xin Yan Pdf

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.

The Brugada Syndrome by Charles Antzelevitch Pdf

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.

Sport-related sudden cardiac death by Pietro Delise,Paolo Zeppilli Pdf

Sudden death in athletes is a global problem. Although it is a relatively rare phenomenon (1/100,000 persons), when it does occur, it is often as an incomprehensible event. In fact, it strikes subjects who presumably should be much healthier than the general population. In the previous 20 years, many authors have studied this problem in an attempt to understand the causes and prevent these events, and it has been determined that, in the vast majority of cases, athletes who die suddenly have an underlying heart disease (arrhythmogenic cardiomyopathy, hypertrophic cardiomyopathy, coronary anomalies, channelopathies, etc.). In most cases these diseases do not produce major symptoms and do not preclude sports activity even at the highest levels, although they do increase the incidence of sudden death. How to discover these diseases in asymptomatic athletes is a hotly debated issue. In particular, there is controversy as to whether all athletes should undergo detailed medical screening, including electrocardiogram, or whether the costs of this screening are too high in relation to the event incidence. The purpose of this book is to accurately analyze the causes of sudden death in athletes and to provide cardiologists and sports physicians with useful tips on how to identify at-risk individuals.

The ECG by Marc Gertsch Pdf

Professor Gertsch covers both clinically relevant ECGs and very interesting rarer cases of the normal and the exercise ECG, making this work extremely comprehensive - it represents the culmination of a lifetime of involvement with invasive and non-invasive cardiology by one of Switzerland's leading cardiologists. Numerous ECGs and two-color drawings illustrate the text, which is also brought closer to the reader by means of over fifty case reports. Ease of reference is facilitated by the division of the text into separate sections: "At a Glance" for readers who want quick information, and "The Full Picture" for readers wishing to go into exhaustive detail. Foreword by Christopher Cannon.

Consults in Obstetric Anesthesiology by Suzanne K. W. Mankowitz Pdf

This text addresses the need for a book specifically aimed at obstetric anesthesia and covers topics such as pulmonary, cardiac renal, hepatic, hematologic, neurologic, endocrine and other diseases. The real anesthetic challenge arises when patients present to Labor and Delivery with unusual or complicated medical problems and, in recent years, a few of the larger institutions have developed an Obstetric Anesthesiology Consultation Service to prepare for the management of these patients. While most pregnant women who present to Labor and Delivery require anesthetic intervention, they typically meet the anesthesiologist for the first time in labor. Since the majority of laboring women are healthy without significant comorbidities, this does not present much of a challenge to the anesthesiologist and the anesthetic management tends to be straight-forward with favorable outcomes. However, using this new model, the anesthesiologist has the opportunity to discuss the various treatment modalities and potentially suggest diagnostic testing to be performed prior to delivery, similar to the pre-operative testing that is done in other surgical environments.
