title: A case of persistent atrial fibrillation cured by focal ablation in a young patient.
abstract: We present a case of a 25-year-old man who had persistent atrial fibrillation (AF) lasting for three months. The persistent AF was terminated by a 20-mg bolus infusion of adenosine triphosphate. Frequent and repetitive episodes of ectopic atrial tachycardia (EAT) emerged from the mid-portion of the saddle between the left superior and inferior pulmonary veins. The successful ablation was achieved by a focal ablation at the site with the earliest activation preceding the P-wave onset by 42 ms, and exhibited a QS pattern in the unipolar recording. This is rare case in which focal ablation could cure persistent AF.
