Book excerpt: The Clinical Cardiac Electrophysiology Handbook, Second Edition, is a concise presentation in outline format of the practical information needed to understand the subtleties of cardiac electrophysiology. The Handbook focuses on the “how-to” management of arrhythmias, along with an understanding of the “why.” “. . . a quick source for information in the EP lab or on the wards offering the ability to quickly review the essential components before a case or to reinforce new notions and practices encountered during a case.” — From the Preface -Fully illustrated with more than 250 figures and tables. -Equally valuable to the cardiology fellow on their electrophysiology rotation, or an EP fellow or technologist working in the EP lab. New and updated sections in the Second Edition: -Ablation energy and biophysics, including pulsed field ablation -AF ablation techniques adjunctive to pulmonary vein isolation -Alternatives to cardiac resynchronization therapy -His bundle pacing -Intracardiac echocardiography -Left atrial appendage occlusion
