Main description:

This provides background information on procedures, epidemiological aspects, problem areas, mortality and morbidity risk. These topics are of particular interest for investigators in ECG research and clinical trials. This monograph is specialized beyond the scope of ordinary clinical textbooks of electrocardiography that have traditionally flooded the market. The authors have closely collaborated for over a quarter of a century in operating an academic ECG Center.
