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.
