title: Multiple distinct right atrial endocardial origins in a patient with atrial tachycardia: mapping and ablation using noncontact mapping.
abstract: Noncontact mapping identified the endocardial origins of four distinct atrial tachycardias in a young patient with drug refractory palpitations and effected successful ablation with no recurrence of symptoms in 5 months of follow-up.
