Over the past 25-30 years, deaths due to Torsades de Pointes (TdP) have resulted in numerous drugs being withdrawn from the market. However, nearly 200 drugs that may prolong the QT interval and cause TdP remain available. A number of drugs with the potential to cause TdP are among the top 200 most prescribed drugs in the US, whilst new information regarding TdP is emerging rapidly. The purpose of this book is to provide a comprehensive source of information on the topic of torsades de pointes (TdP), which is a life-threatening polymorphic ventricular tachyarrhythmia associated with QT interval prolongation on the electrocardiogram (ECG). Torsades de Pointes provides a detailed, up-to-date and emerging information related to the epidemiology, drug culprits, mechanisms, risk factors, and methods of prevention and management of the life-threatening polymorphic ventricular tachycardia, also known as torsades de pointes. The book contains current knowledge, incorporating recent and cutting-edge advances in understanding of topics including inherited channelopathies and congenital LQTS; drugs that cause QT interval prolongation and TdP; non-drug causes of acquired QT interval prolongation and TdP; epidemiology of inherited and acquired TdP; morbidity and mortality associated with TdP, particularly in association with specific antimicrobials, antidepressants and antipsychotics, and methadone; cellular and molecular mechanisms of TdP, traditional and emerging risk factors for TdP; methods of prevention and risk reduction for TdP; and clinical management of patients with TdP. This book is an essential reference for both clinicians and researchers – providing guidance for clinicians who care for patients receiving QT interval-prolonging drugs, as well as cutting edge information for scientists and investigators conducting research in the area. Up-to-date information on TdP associated with inherited channelopathies and the multiple forms of congenital LQTS Includes a wealth of new information emerging regarding TdP, including newly-described risk factors and cellular and molecular mechanisms, contributions of genetic polymorphisms to drug-induced TdP, methods of quantification of risk, and methods of risk reduction, including clinical decision support Contains information on nearly 200 commonly used drugs that have the potential to cause torsades de pointes, including antimicrobials, antipsychotics, antidepressants, antiarrhythmic agents, methadone, and many others An essential reference for clinicians and researchers – provides guidance for clinicians who care for patients receiving QT interval-prolonging drugs, as well as cutting edge information for scientists and investigators conducting research in the area
In recent years there has been considerable interest in the diagnosis and understanding of ventricular repolarisation, particularly the QT interval prolongation and abnormal T and T/U wave morphology associated with torsades de pointes. Advances in ion channel cloning have greatly improved our understanding of the role of ionic channels in mediating cardiac repolarisation. Unfortunately, it is increasingly recognised that a number of drugs, both those associated with altering repolarisation, and others for non-cardiac conditions can increase the propensity for polymorphic ventricular tachycardia, syncope and even ventricular fibrillation and sudden death. In this volume, arrhythmia specialists from St. George’s Hospital Medical School, London discuss the mechanisms behind QT prolongation and torsades de pointes. They focus particularly on the risk of individual cardiac and non-cardiac drugs in provoking long QT syndrome, providing a comprehensive review which will be useful for all electrophysiologists treating polymorphic ventricular tachycardias, and will expose important regulatory issues for pharmaceutical authorities and for the wider medical community.

Current regulatory guidelines for cardiac safety utilize hERG block and QT interval prolongation as risk markers. This strategy has been successful at preventing harmful drugs from being marketed, but criticized for leading to early withdrawal of potentially safe drugs. Here we collected a series of articles presenting new technological and conceptual advances, including refinement of ex vivo and in vitro assays, screens and models, and in silico approaches reflecting the increasing effort that has been put forward by regulatory agencies, industry, and academia to try and address the need of a more accurate, mechanistically-based paradigm of proarrhythmic potential of drugs. This Research Topic is dedicated to the memory of Dr. J. Jeremy Rice, our wonderful friend and colleague.
Sex and Cardiac Electrophysiology: Differences in Cardiac Electrical Disorders Between Men and Women is a comprehensive investigation into all aspects of sex differences in cardiac electrophysiology. As there are substantial differences between female and male patients in physiology, pathology triggering factors, disease progression, clinical approaches and treatment outcome, this book provides a comprehensive examination. In cardiology, the differences between women and men are more recognized, hence this title summarizes these important differences, providing the essential information needed for clinical specialists and researchers involved in the design and implementation of clinical studies. Explores topics ranging from the physiologic differences between women and men to the differences in clinical handling of arrhythmic disorders between female and male patients Provides sex differences in cardiac electrophysiology in separate chapters Covers the sex differences of cardiac electrical disorders, providing insights beyond cardiac metabolic syndrome, hypertension, atherogenesis and heart failure

This comprehensive book provides reviews of pain management complications that arise in clinical practice. Organized into sections focused on types of pain therapy and procedures, each chapter is based on actual complications; starting with a case description that delineates the context with a short past medical and surgical history, pain management technique and outcome it is followed by a comprehensive review of the topic described in the first section. Authors emphasize the elements of differential diagnosis that pointed towards establishing of the complication and describe the best way to treat the identified complication. Physicians treating pain patients will be presented the necessary tools in identifying and treating unanticipated complications following pain interventions, thus providing safer care for their patients.

Diagnostic Molecular Pathology: A Guide to Applied Molecular Testing is organized around disease types (genetic disease, infectious disease, neoplastic disease, among others). In each section, the authors provide background on disease mechanisms and describe how laboratory testing is built on knowledge of these mechanisms. Sections are dedicated to general methodologies employed in testing (to convey the concepts reflected in the methods), and specific description of how these methods can be applied and are applied to specific diseases are described. The book does not present molecular methods in isolation, but considers how other evidence (symptoms, radiology or other imaging, or other clinical tests) is used to guide the selection of molecular tests or how these other data are used in conjunction with molecular tests to make diagnoses (or otherwise contribute to clinical workup). In addition, final chapters look to the future (new technologies, new approaches) of applied molecular pathology and how discovery-based research will yield new and useful biomarkers and tests. Diagnostic Molecular Pathology: A Guide to Applied Molecular Testing contains exercises to test readers on their understanding of how molecular diagnostic tests are utilized and the value of the information that can be obtained in the context of the patient workup. Readers are directed to an ancillary website that contains supplementary materials in the form of exercises where decision trees can be employed to simulate actual clinical decisions. Focuses on the menu of molecular diagnostic tests available in modern molecular pathology or clinical laboratories that can be applied to disease detection, diagnosis, and classification in the clinical workup of a patient Explains how molecular tests are utilized to guide the treatment of patients in personalized medicine (guided therapies) and for prognostication of disease Features an ancillary website with self-testing exercises where decision trees can be employed to simulate actual clinical decisions Highlights new technologies and approaches of applied molecular pathology and how discovery-based research will yield new and useful biomarkers and tests
