The year 1988 marked the beginning of the International Workshop on Cardiac Arrhythmias. This biannual series of meetings was initiated with the following goals: (1) to present technological advances in the field of cardiac arrhythmias, (2) to publicise the results of current research, and (3) to assess the impact of new diagnostic and therapeutic approaches. In addition, by bringing together experts in this field, controversial aspects in the diagnosis and treatment of cardiac arrhythmias could be discussed, allowing a consensus to be reached regarding the evaluation and management of specific disease conditions. The success achieved in reaching these goals and the utility of the workshops have been confirmed by.
