Abstract:
:Body surface potential maps have and certainly will have a very important role in the field of clinical arrhythmology, specifically for the localization of accessory pathways, for the detection of the origin of ventricular arrhythmias and for the identification of patients at risk of sudden death. In this particular setting, surface maps are certainly more useful than other more costly and sophisticated imaging techniques.
