Table 3 compares the electrophysiological parameters between the wide-type AF model and PITX2+/− deficiency model, which reflected the left atrial anatomy and electrophysiology of 25 patients (68.0% male, 59.8 ± 9.8 years old, 32.0% paroxysmal AF). Here, PITX2 is linked to Paroxysmal atrial fibrillation.
