OBJECTIVE The purpose of this study was to describe the surface electrocardiogram (ECG) morphology of common atrial tachycardias (ATs) that occur after pulmonary vein (PV) isolation. BACKGROUND Focal ATs from reconnected PVs and macroreentrant mitral annular (MA) flutter are the most common form of ATs occurring after PV isolation. METHODS Patients with persistent AT after PV isolation underwent mapping and ablation. Tachycardia origin and mechanism were determined using electroanatomic… CONTINUE READING
