First multi-year cumulation covers six years: 1965-70.
In recent years, catheter ablation of atrial fibrillation has become a widespread treatment modality in electrophysiology laboratories all over the world. Nevertheless, many aspects of the therapy are controversial. Developed by world-renowned experts in the field, this book presents a comprehensive and up-to date overview of all the most important and debated aspects of atrial fibrillation ablation, including: • Ablation techniques and technologies • Procedural endpoints • Patient management pre-, peri- and post-ablation • Anticoagulation issues • Prevention and treatment of complications • Definition of success and long-term results The text expands upon the content of the VeniceChart international consensus document on atrial fibrillation ablation and is enriched by several explanatory figures and tables. It provides a highly valuable source of information not only for researchers and specialists in electrophysiology, but also for general cardiologists, internists, fellows in cardiology and medical students.
This open access textbook offers a guide to corporate finance for modern companies that want to create long-term value. Drawing on recent literature on sustainable companies, it starts by analysing the Sustainable Development Goals as a strategy for the transition to a sustainable economy. Next, it translates the general concept of sustainability into core corporate finance methods, such as net present value, company valuation, cost of capital, capital structure and M&A. Current corporate finance textbooks are primarily based on the shareholder model, designed to maximise financial value. This book instead adopts the integrated model, which argues that companies have to serve the interests o...
This work provides methods to measure and analyze features of atrial electrograms - especially complex fractionated atrial electrograms (CFAEs) - mathematically. Automated classification of CFAEs into clinical meaningful classes is applied and the newly gained electrogram information is visualized on patient specific 3D models of the atria. Clinical applications of the presented methods showed that quantitative measures of CFAEs reveal beneficial information about the underlying arrhythmia.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
The atrial substrate undergoes electrical and structural remodeling during atrial fibrillation. Detailed multiscale models were used to study the effect of structural remodeling induced at the cellular and tissue levels. Simulated electrograms were used to train a machine-learning algorithm to characterize the substrate. Also, wave propagation direction was tracked from unannotated electrograms. In conclusion, in silico experiments provide insight into electrograms' information of the substrate.
