Randomized Controlled Trial Comparative StudyFast atrial activity predicts recurrence of atrial fibrillation after pulmonary vein isolation: results from a prospective randomized study.
Recurrence of atrial fibrillation (AF) after ablative treatment is common. We hypothesized that AF recurrence is heralded by fast ectopic atrial activity occurring after electrical reconnection of previously isolated pulmonary veins. ⋯ In patients with atrial fibrillation and after the first PVI procedure, appearance of symptomatic fast atrial activity is associated with a high risk of AF recurrence. Re-isolation of reconnected pulmonary veins in these pts significantly reduces the risk of AF recurrence.
