The "common form" or "usual"<unk>  utilizes the slow AV nodal pathway as the anterograde limb of the circuit and the fast AV nodal pathway as the retrograde limb.Uncommon form of<unk>  is reentry circuit reversed in a format that AV nod pathway is anterograde limb and slow AV nodal pathway is the retrograde limb. third type of<unk>  that utilizes the slow AV nodal pathway as the anterograde limb and left atrial fibers that approach the AV node from the left side of the inter-atrial septum as the retrograde limb.
