title: Dual mechanisms underlying pulmonary vein tachycardias in a patient with paroxysmal atrial fibrillation.
abstract: We report a case of a 46-year-old man with paroxysmal atrial fibrillation who underwent pulmonary vein isolation. After a complete isolation of each pulmonary vein was performed, two different types of pulmonary vein tachycardia appeared: a regular tachycardia in the left inferior pulmonary vein with a supposed reentrant mechanism, and an irregular tachycardia in the right superior PV showing a nonreentrant character.
