The AFL exhibited positive P waves in the inferior leads and lead V1. Left atrial activation mapping revealed 2 remote sites with early activation that were located at the antrum of the left superior PV roof and the left inferior PV bottom. A single irrigated radiofrequency ablation targeting the earliest PV activation at the left PV carina eliminated the AFL. This case demonstrated that PV carina tachycardia with multiple conduction gaps and inter-PV conduction after PVI might mimic double focal atrial tachycardias.
