This book was released on 2020-03-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand cardiac implantable electronic device (CIED) management, the clinician requires a foundation of information regarding CIED purpose, design and function, as well as experience in interpreting CIED output, i.e., electrical assessment of the system, programmed parameters, electrograms, and markers. In addition, one must be able to correlate and interpret the accompanying electrocardiographic tracing with the patient’s clinical presentation. For students of CIED management, be they beginners in the field or more advanced, there is always an appreciation for case studies, i.e., real-world examples of managing a specific device-related issue. To this end, this workbook of 61 device management case studies has been prepared by six talented RN Device Specialists and three physicians involved in the Heart Rhythm Service practice at the Mayo Clinic in Rochester, Minnesota. Included in the case studies are examples from pacemakers, ICDs and CRT devices, illustrating interpretation and management of a variety of device behaviors, some with abnormal function that requires diagnosis and management approach, and others that display appropriate behavior of a specific device algorithm that may be confusing for the CIED student. ~David L. Hayes, MD, and the contributors – adapted from the Preface. -Perfect for exam prep, training across CIED devices, and as a reference to keep on hand in the lab. -Real-world examples of managing a specific device-related issue. -Includes straightforward clinical management issues to more complex issues that may be related to a specific device algorithm.

Modern implantable devices (pacemakers, defibrillators, tools for continuous monitoring and resynchronization therapy) and treatment methods, including minimally invasive surgery (ablation, implantation), have been developed for managing cardiac rhythm and avoiding heart failure. In addition to electrical pacing, ablation is an effective minimally invasive surgical method for reducing and blocking arrhythmic phenomena, both as an independent treatment method or in conjunction with pacing therapy. This book discusses modern cardiac rhythm management methods and devices as well as some important medical aspects of their use.

Available in PDF, EPUB and Kindle. Book excerpt: Different artificial tools, such as heart-pacing devices, wearable and implantable monitors, engineered heart valves and stents, and many other cardiac devices, are in use in medical practice. Recent developments in the methods of cardiac pacing along with appropriate selection of equipment are the purpose of this book. Implantable heart rate management devices and wearable cardiac monitors are discussed. Indications for using specific types of cardiac pacemakers, cardiac resynchronization therapy devices, and implantable cardioverter defibrillators (ICDs) are of interest and their contraindications are considered. Special attention is paid to using leadless devices. The subcutaneous ICD obviates the need for transvenous leads and leadless pacemakers are entirely implantable into the right ventricle. Finally, applications of user-friendly wearable devices for the detection of atrial arrhythmia are debated.

Available in PDF, EPUB and Kindle. Book excerpt: In the last years, indications for defibrillators and cardiac resynchronization therapy have expanded enormously; for this reason, and also due to the extension of human life length, the number of patients with implanted cardiac devices have steadily increased. The leads implanted for the functioning of these devices, however, have a limited duration in time and more and more their extraction will be a frequent issue in clinical practice, in order to treat short- and long-term complications, such as infections and failures. Aim of this book is to provide readers with a state-of-the-art on lead extraction techniques. The chapters deal with leads characteristics, indications to lead removal, patient preparation, tools and techniques for extraction, and prevention and management of complications. In addition, a series of tips and tricks on how to treat some particular conditions (tight cost-clavicular space, fractured leads, ICD leads, dangered leads...etc.), are given. A new extracting technique, according to which the extraction is performed through the internal jugular vein is described; several examples are included and many figures provide a thorough depiction of this innovative procedure. The volume will be an excellent resource for all those involved in the management of cardiac patients: cardiologists, arrhythmologists, cardiac surgeons, GPs, pediatricians, and post-graduate students in these disciplines.

Book excerpt: Today hundreds of thousands of Americans carry pacemakers and implantable cardioverter-defibrillators (ICDs) within their bodies. These battery-powered machines—small computers, in fact—deliver electricity to the heart to correct dangerous disorders of the heartbeat. But few doctors, patients, or scholars know the history of these devices or how "heart-rhythm management" evolved into a multi-billion-dollar manufacturing and service industry. Machines in Our Hearts tells the story of these two implantable medical devices. Kirk Jeffrey, a historian of science and technology, traces the development of knowledge about the human heartbeat and follows surgeons, cardiologists, and engineers as they invent and test a variety of electronic devices. Numerous small manufacturing firms jumped into pacemaker production but eventually fell by the wayside, leaving only three American companies in the business today. Jeffrey profiles pioneering heart surgeons, inventors from the realms of engineering and medical research, and business leaders who built heart-rhythm management into an industry with thousands of employees and annual revenues in the hundreds of millions. As Jeffrey shows, the pacemaker (first implanted in 1958) and the ICD (1980) embody a paradox of high-tech health care: these technologies are effective and reliable but add billions to the nation's medical bill because of the huge growth in the number of patients who depend on implanted devices to manage their heartbeats.
