This book covers the main mathematical and numerical models in computational electrocardiology, ranging from microscopic membrane models of cardiac ionic channels to macroscopic bidomain, monodomain, eikonal models and cardiac source representations. These advanced multiscale and nonlinear models describe the cardiac bioelectrical activity from the cell level to the body surface and are employed in both the direct and inverse problems of electrocardiology. The book also covers advanced numerical techniques needed to efficiently carry out large-scale cardiac simulations, including time and space discretizations, decoupling and operator splitting techniques, parallel finite element solvers. These techniques are employed in 3D cardiac simulations illustrating the excitation mechanisms, the anisotropic effects on excitation and repolarization wavefronts, the morphology of electrograms in normal and pathological tissue and some reentry phenomena. The overall aim of the book is to present rigorously the mathematical and numerical foundations of computational electrocardiology, illustrating the current research developments in this fast-growing field lying at the intersection of mathematical physiology, bioengineering and computational biomedicine. This book is addressed to graduate student and researchers in the field of applied mathematics, scientific computing, bioengineering, electrophysiology and cardiology.
ICD therapy has become the standard form of treatment for ventricular tachyarrhythmias. With clinical data showing its efficacy in both secondary and primary prevention of premature sudden death, its use is likely to increase dramatically in the next decade. Technological advancement has been instrumental in simplifying ICD implantation. However, technical additions to the device have also made its scope of functions more complex. In addition to providing rapid and effective therapy for ventricular tachycardia and fibrillation, the ICD is now capable of providing a full spectrum dual-chamber pacing as well as therapies for atrial fibrillation. Soon, it will also be able to provide treatment for congestive heart failure using multi-site ventricular pacing and provide continuous hemodynamic monitoring. This book serves as an introductory text to those who are relatively new to this technology. In its manual form, it outlines the pertinent components of ICD functions and the basic differences among the various models. It provides practical points in ICD implantation, and in its programming and trouble-shooting.
SmartBook is the first and only adaptive reading experience designed to change the way students read and learn. It creates a personalized reading experience by highlighting the most impactful concepts a student needs to learn at that moment in time. As a student engages with SmartBook, the reading experience continuously adapts by highlighting content based on what the student knows and doesn t know. This ensures that the focus is on the content he or she needs to learn, while simultaneously promoting long-term retention of material. Use SmartBook s real-time reports to quickly identify the concepts that require more attention from individual students or the entire class."
This book addresses the application of simulation modelling techniques in order to enable better informed decisions in business and industrial organisations. The book's unique approach treats simulation not just as a technical tool, but as a support for organisational decision making, showing the results from a survey of current and potential users of simulation to suggest reasons why the technique is not used as much as it should be and what are the barriers to its further use.
Echocardiography has now reached its maturity and plays a key role in the clinical assessment of cardiac function. However, its ability to assess myocardial perfusion remains a clinical challenge.
Myocardial contrast echocardiography is a technique that uses microbubbles. These microbubbles remain entirely within the intravascular space and their presence in any myocardial region denotes the status of microvascular perfusion within that region. During the last few years, a large number of research studies have been dedicated to this topic. The latest developments in echocardiographic techniques and second-generation contrast agents allow for the potential assessment of myocardial perfusion and provide an accurate endocardial border delineation.
In the present book, these new echocardiographic techniques dedicated to the assessment of myocardial perfusion are described in detail by experts from both sides of the Atlantic. Tips and tricks are included, explaining the basic concepts that are needed to understand and perform contrast echocardiography.
