简要总结

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.

结局指标

主要结局

Correlation between conduction velocity and MRI fibrosis.

时间窗: Baseline

The conduction velocity in sinusal rhythm and with extra estimuli will be correlated with the MRI late gadolinium enhancement sequence (MRI-LGE).

次要结局
