Accurate mapping of the site of origin and activation sequence of a cardiac arrhythmia is essential for a successful radio frequency (RF) catheter ablation procedure. The CARTO™ system is a new, non-fluoroscopic, method for mapping designed to associate a specific intracardiac electrocardiogram with the endocardial location from which it has been recorded. Thus, for the first time, the CARTO™ system allows a precise correlation of electrophysiological information with cardiac anatomy. The system records through a special catheter, and then displays on its computer screen, the precise 3-D electro-anatomical maps of the different cardiac chambers. The maps are reconstructed by integrating the information from recorded intracardiac electro-grams with their precise anatomic location within the heart. The method is based on the ability to connect a new locatable catheter with a system for endocardial navigation and mapping. Even though the cardioarrhythmological protocol represents today a basic guide to assess the eligibility of competitive athletes with suspected or documented arrhythmias, the time has come to revise it. In fact, over the past years new diagnostic and therapeutic tools have come available in the field of clinical and sports arrhythmology.
