Severe disorders of the heart rhythm that can cause syncope or sudden cardiac death (SCD), can be treated by radio-frequency (RF) catheter ablation. The precise localization of the arrhythmogenic site and the positioning of the RF catheter over that site are problematic: they can impair the efficiency of the procedure and are time consuming (several hours). Our approach consists of integrating fluoroscopic and electrical data from the RF catheters into the same image so as to better guide RF ablation, shorten the duration of this procedure and increase its efficacy.
