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.

Eligibility
Inclusion criteria
* Atrial fibrillation paroxysmal or persistent with criteria for percutaneous ablation
Exclusion criteria
* Cardiomiopathy (FEVI\<40%) or significant valvulopathy. * MRI not possible or contraindicated. * Previous atrial fibrillation ablation.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between conduction velocity and MRI fibrosis. | Baseline | The conduction velocity in sinusal rhythm and with extra estimuli will be correlated with the MRI late gadolinium enhancement sequence (MRI-LGE). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between voltage and MRI fibrosis. | Baseline | The voltage in sinus rhythm and in atrial fibrillation will be correlated with the MRI-LGE. |
| Correlation between electrocardiographic image (ECGi) and MRI-LGE. | Baseline | The xxx of the ECGi will be correlated with the MRI-LGE. |
