Abstract
Previous studies in patients with antidromic reciprocating tachycardia (ART ) have observed a critical anatomic requirement (> 4 cm) between an antegra de bypass tract limb and a retrograde AV nodal limb. We report two patients with AAT utilizing a paraseptal accessory pathway. in both cases, a critic al degree of slow conduction within the circuit provides unusual electrophy siologic substrate to overcome the expected anatomical constraints.
