Brief Summary:
The study aims to assess the right and left atrial electrophysiological substrate in atrial fibrillation patients using the invasive electroanatomic map (basal and with extraestimulus) as well as its correlation with cardiac magnetic resonance and electrocardiographic imaging. The results will also be compared when the patient is in sinus rhythm and atrial fibrillation.

Primary Outcome Measures :
  1. Correlation between conduction velocity and MRI fibrosis. [ Time Frame: Baseline ]
    The conduction velocity in sinusal rhythm and with extra estimuli will be correlated with the MRI late gadolinium enhancement sequence (MRI-LGE).

Secondary Outcome Measures :
  1. Correlation between voltage and MRI fibrosis. [ Time Frame: Baseline ]
    The voltage in sinus rhythm and in atrial fibrillation will be correlated with the MRI-LGE.

  2. Correlation between electrocardiographic image (ECGi) and MRI-LGE. [ Time Frame: Baseline ]
    The xxx of the ECGi will be correlated with the MRI-LGE.
