| crt therapy for heart failure: Implantable Defibrillator Therapy: A Clinical Guide Antonio Pacifico, Philip D. Henry, 2002-08-31 Implantable defibrillators as originally conceived by Michel Mirowski were limited to the detection and automatic termination of ventricular fibrillation. In the original AID device, the detection algoritlun sought to distinguish sinus rhytlun from ventricular fibrillation by identifying the more sinusoidal waveform of ventricular fibrillation. The therapeutic intervention was elicited only once deadly polymorphic rhythms had developed. It was rapidly learned, however, that ventricular fibrillation is usually preceded by ventricular tachycardia. Mirowski recognized the pivotal importance of developing algoritllms based on heart rate. Ventricular tachycardia detection allowed the successful development of interventions for the termination of ventricular tachyarrhythmias before they degenerated into ventricular fibrillation. Current device therapy no longer confines itself to tlle termination of chaotic rhythms but seeks to prevent them. Diagnostic algorithms moved upward along the chain of events leading to catastrophic rhytlulls. Rate smoothing algorithms were developed to prevent postextrasystolic pauses from triggering ventricular and atrial tachyarrhytlmlias. Beyond the renaissance of ectopy-centered strategies, long-term prevention received increasing attention. Multisite pacing therapies provided by Arrhythmia Management Devices were designed to reduce the arrhytlunia burden and optimize the synergy of cardiac contraction and relaxation. Clinical evidence now suggests that atrial fibrillation prevention by pacing is feasible and tllat biventricular pacing may be of benefit in selected patients with heart failure. However, these applications of device therapy that generally require ventricular defibrillation backup remain investigational and were not considered in this book. |

| crt therapy for heart failure: Cardiac Resynchronization Therapy for Congestive Heart Failure Department of Health & Human Services, Agency for Healthcare Research and Quality, 2014-05-25 Heart failure is the fastest growing cardiovascular diagnosis in North America, and it carries a poor prognosis. To improve survival in heart failure patients, therapies need to reduce either sudden cardiac death (the most common cause of death in patients with New York Heart Association [NYHA] Class I or II symptoms) or progressive heart failure (the predominant cause of death in those with NYHA Class III or IV symptoms). Electrical conduction disturbances are common in heart failure and are associated with increased mortality risk. Atrial-synchronized biventricular pacing (cardiac resynchronization therapy [CRT]) addresses many of the pathophysiological changes seen in patients with wide QRS complexes in whom delayed activation of the left free wall results in mechanical dyssynchrony. The University of Alberta Evidence-based Practice Center conducted a systematic review to examine the success rate and safety of biventricular pacemaker implantation and the efficacy of CRT in patients with heart failure. Further, the researchers used these data in a decision analysis to evaluate the incremental cost effectiveness of CRT versus medical therapy alone. This report addresses the following questions: 1. In adult patients with symptomatic heart failure, is CRT more effective than optimal medical care alone? 2. Is the implantation of a CRT system safe for patients? 3. What is the role of CRT in the treatment of heart failure? 4. What is the cost-effectiveness of CRT in patients with congestive heart failure? |
| crt therapy for heart failure: Primary Care in Practice Oreste Capelli, 2016-05-11 The development of the Chronic Care Model (CCM) for the care of patients with chronic diseases has focused on the integration of taking charge of the patient and his family within primary care. The major critical issues in the implementation of the CCM principles are the non-application of the best practices, defined by EBM guidelines, the lack of care coordination and active follow-up of clinical outcomes, and by inadequately trained patients, who are unable to manage their illnesses. This book focuses on these points: the value of an integrated approach to some chronic conditions, the value of the care coordination across the continuum of the illness, the importance of an evidence-based management, and the enormous value of the patients involvement in the struggle against their conditions, without forgetting the essential role of the caregivers and the community when the diseases become profoundly disabling. |

| crt therapy for heart failure: Electrocardiographic Imaging Maria S. Guillem, Carlos Figuera, Linwei Wang, 2020-04-17 Electrical activity in the myocardium coordinates the contraction of the heart, and its knowledge could lead to a better understanding, diagnosis, and treatment of cardiac diseases. This electrical activity generates an electromagnetic field that propagates outside the heart and reaches the human torso surface, where it can be easily measured. Classical electrocardiography aims to interpret the 12-lead electrocardiogram (ECG) to determine cardiac activity and support the diagnosis of cardiac pathologies such as arrhythmias, altered activations, and ischemia. More recently, a higher number of leads is used to reconstruct a more detailed quantitative description of the electrical activity in the heart by solving the so-called inverse problem of electrocardiography. This technique is known as ECG imaging. Today, clinical applications of ECG imaging are showing promising results in guiding a variety of electrophysiological interventions such as catheter ablation of atrial fibrillation and ventricular tachycardia. However, in order to promote the adoption of ECG imaging in the routine clinical practice, further research is required regarding more accurate mathematical methods, further scientific validation under different preclinical scenarios and a more extensive clinical validation |

| crt therapy for heart failure: The Breathless Heart Michele Emdin, Alberto Giannoni, Claudio Passino, 2016-11-25 This book systematically focuses on central sleep apneas, analyzing their relationship especially with heart failure and discussing recent research results and emerging treatment strategies based on feedback modulation. The opening chapters present historical background information on Cheyne-Stokes respiration (CSR), clarify terminology, and explain the mechanics and chemistry of respiration. Following a description of the physiology of respiration, the pathophysiology underlying central apneas in different disorders and particularly in heart failure is discussed. The similarities and differences of obstructive and central apneas are then considered. The book looks beyond the concept of sleep apnea to daytime CSR and periodic breathing during effort and contrasts the opposing views of CSR as a compensatory phenomenon or as detrimental to the failing heart. The diagnostic tools currently in use for the detection of CSR are thoroughly reviewed, with guidance on interpretation of findings. The book concludes by describing the various forms of treatment that are available for CSR and by explaining how to select patients for treatment. |

| crt therapy for heart failure: Cardiac Pacemakers Step by Step S. Serge Barold, Roland X. Stroobandt, Alfons F. Sinnaeve, 2008-04-15 Over the years we have heard many complaints that there is no verysimple book on cardiac pacing for real beginners. We have alsoheard that all the books on cardiac pacing are too complicated andimpossible to understand by beginners. Many have voiced the hopethat one day someone would write a book in the same style asDubin’s book on basic electrocardiography which is a hugebestseller with well over a million sold in many languages. A‘Dummy’ book on cardiac pacing would appeal to nurses,cardiology technicians, medical students and pacemaker companiesfor training their staff. We started with the assumption that the reader would know theprinciples of electrocardiography as in Dubin’s book butnothing about cardiac pacing. We carefully studied the Dubin bookand believe that we have improved his teaching method. The bookconsists of numbered illustrations each illustrating a concept inthe form of a diagram drawn professionally. We have been careful tomake the artwork simple for easy comprehension. Each illustration will occupy a page and have several lines oftext below it. We have already completed most of these. It isessential that there are all in color, this is a unique sellingpoint. The 3 authors have had vast experience in the field. Dr Baroldhas published 10 books on cardiac pacing and wrote the section oncardiac pacing in the 4th and 5th Edition of Braunwald’sbook, Heat Disease. S. Serge Barold, Roland Stroobandt and Alfons Sinnaeve Content: The plates depicting a concept with occupy 1 pages. Each plateconsists of a diagram and a short text. All diagrams are in color. In black and white they would losetheir teaching value There will be approx 200 plates. There will be approx 100 electrocardiograms. There will be a glossary, appendices and index |
