Featuring a comprehensive collection of intracardiac recordings, fluoroscopic images, and electroanatomic maps, this book is a practical, concise but complete guide to diagnosis and ablation of cardiac arrhythmias in the electrophysiology laboratory. Each chapter focuses on a specific arrhythmia and presents a systematic discussion of diagnostic and ablation criteria, followed by an atlas of electrophysiologic recordings. These illustrations demonstrate all key aspects of the arrhythmia: electrophysiologic features, mode of induction and termination, response to diagnostic pacing maneuvers, classic presentations, unusual manifestations, mapping techniques, and target site criteria for ablation.
