Abstract :
Predictability of catheter ablation (CA) outcome in persistent atrial fibrillation (AF) is still an open issue. Predictors in previous studies are mainly computed in only one ECG lead, and neglect relevant information from the other ones. In this study we investigate the role of interlead relationships on the 12-lead ECG in CA outcome prediction.
