Actual (reported)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.

Actual (reported)Correlation between conduction velocity and MRI fibrosis.
The conduction velocity in sinusal rhythm and with extra estimuli will be correlated with the MRI late gadolinium enhancement sequence (MRI-LGE).
Baseline
Correlation between voltage and MRI fibrosis.
Baseline
Correlation between electrocardiographic image (ECGi) and MRI-LGE.
Baseline
Patients with persistent or paroxysmal atrial fibrillation, without cardiomyopathy (LVEF\> 40%) or significant valvulopathy who will undergo first AF ablation.
