Signal Averaged Electrocardiography Concepts, Methods and Applications

This book deals with the basic concepts of high resolution electrocardiography: the electrophysiological basis of late potentials, mechanism of arrhythmias, the different methods of recording and analysis of high resolution, signal processed electrocardiograms and their clinical applications.
This is a new edition and is more up-to-date, provides more clinical utility and addresses more basic concepts of the electrophysiology of re-entrant arrhythmias than any other book published in the same field. The book will appeal to cardiologists (academic and clinical), electrophysiologists, technicians and engineers working in the field of computerized electrocardiography and in industry.
