Since the publication of the popular first edition, significant breakthroughs have been made in the field of cardiac mapping and catheter ablation of arrhythmias. This text offers an evaluation of the entire spectrum of cardiac mapping and is a unique source of information on the latest developments in the field. International authorities recognised for their contribution to the development of mapping techniques and to the treatment of arrhythmias cover every aspect of the subject, from historical perspectives to future trends, and present an expert review of the value of the technique as a diagnostic tool. This new edition, with over 50% new material and many new contributors, includes discussion of technical advances in non-contact and non-floroscopic mapping, and critical editorial comments by pioneers in each specific area. Cardiac Mapping remains a central resource for the interventional electrophysiologist, rhythmologist and all those interested in understanding the mechanisms of cardiac arrhythmia.
