Electrophysiology studies test the electrical activity of the heart to determine the source of an arrhythmia. This book is a comprehensive guide to cardiac electrophysiology providing a thorough understanding of the mechanisms of arrhythmias and therapeutic interventions used in their treatment. Beginning with an introduction to cardiac electrophysiology and the fundamentals of cardiac anatomy, imaging, mapping and ablation, the following sections cover the diagnosis and management of different types of arrhythmia. The final section discusses miscellaneous topics including entrainment, provocative drug testing in the electrophysiology lab, and catheter ablation in children. The book is highly illustrated with nearly 300 images and tables and each chapter concludes with a summary highlighting the main points of the topic and offers suggestions for further reading.
