Revisiting Para-Septal Accessory Pathways: A Unified Anatomic, Electrocardiographic, and Electrophysiologic Framework for Typical and Variant Subtypes
{{output}}
Accessory pathways (APs) are classified as typical or variant according to their atrial and ventricular insertions. Typical APs connect atrial and ventricular working myocardium directly across the annulus, whereas variant APs-including the atrio-Hisian pathwa... ...
