Book Description
Dynamic electrocardiograms were recorded from 1,108 patients on 1,421 occasions in an attempt to evaluate the association of ventricular arrhythmias with the presence or absence of significant symptomatology in a predominantly ambulatory population. The detailed statistical analysis of the ventricular arrhythmias encountered in these recordings are presented in this paper. Since paroxysmal ventricular tachycardia (PVT) is considered to be an extremely ominous arrhythmia, its occurrence in the study was analyzed in detail and the results are discussed.

Book Description
This book provides an excellent overview of the diagnosis of abnormal electrocardiograms (ECGs) through deep learning methods. These methods include optimal techniques that can link the processing and analysis of nonstationary ECG signals, the various statistical methods of converting ECG data into variant maps, and the application of various ways of identifying premature atrial beats, ECG characteristics of right and left ventricular tachyarrhythmia, and conditions producing left ventricular hypertrophy, including hypertrophic cardiomyopathy. This book is divided into two sections, including basic and practical applications of ECGs. We hope that it will serve as a reference for the techniques used to obtain and process electrical signals for ECGs. This book will also function as an excellent reference for atrial and ventricular tachyarrhythmia.

Book Description
This book provides a comprehensive review of the ECG findings of inherited arrhythmias and cardiomyopathies. Despite new forms of medical imaging, electrocardiography (ECG) remains the cornerstone of diagnosis, risk-stratification, and prognosis for these conditions. It is extremely important for clinicians to develop the skills required to interpret the ECG correctly as both overdiagnosis and underdiagnosis of these conditions can have a deleterious effect on patients and their families. Each chapter covers a specific condition and highlights typical or critically important ECG findings. Chapters include detailed descriptions of these findings along with pathophysiological mechanisms and clinical vignettes. In addition, the book reviews some normal ECG findings in athletes in order to differentiate some ECG findings from those which may be found in inherited arrhythmia or cardiomyopathy conditions. Electrocardiography of Inherited Arrhythmias and Cardiomyopathies: From Basic Science to Clinical Practice is an essential resource for physicians, residents, fellows, and medical students in cardiology, cardiac electrophysiology, emergency medicine, sports medicine, and primary care.

Book Description
This book deals with the basic concepts of high resolution electrocardiography: the electrophysiological basis of late potentials, mechanism of arrhythmias, the different methods of recording and analysis of high resolution, signal processed electrocardiograms and their clinical applications. This is a new edition and is more up-to-date, provides more clinical utility and addresses more basic concepts of the electrophysiology of re-entrant arrhythmias than any other book published in the same field. The book will appeal to cardiologists (academic and clinical), electrophysiologists, technicians and engineers working in the field of computerized electrocardiography and in industry.

Book Description
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.
