Summary: This book presents the features of Wolff-Parkinson-White and other preexcitation syndromes with detailed discussion of the management and treatment of these patients. Catheter ablation has become a curative first-line treatment for circus movement tachycardias involving accessory pathway conduction. However, diagnostic and interventional challenges may be associated with anatomically and electrophysiologically complex single accessory pathway conduction, multiple accessory pathways, accessory pathways with other coexistent tachycardias, including atrioventricular nodal reentrant tachycardia and atrial tachycardias, and accessory pathways with coexistent congenital heart disease. The complexity involved requires a thorough theoretical and practical knowledge for performing unequivocally conclusive/meaningful electrophysiological testing and successful catheter ablation. This book is based on the authors personal long-term experience and contains over 700 illustrations of intracardiac recordings and fluoroscopic images, as well as clear and user-friendly descriptions of the electrophysiologic data, its analysis and interpretation. It therefore offers a comprehensive practical guide for mapping and catheter ablation. The systematic approach is also invaluable for accessory pathways coexistent with other arrhythmias or congenital heart diseases. Wolff-Parkinson-White and Other Preexcitation Syndromes presents the topic as a fascinating part of clinical cardiac electrophysiology and all types of corresponding accessory pathways, which are often associated with diagnostic and interventional challenges. It therefore provides an invaluable educational resource to further scientific and medical knowledge in the topic and will be essential reading for all electrocardiologists and any medical professional that manages these patients.
