<unk><unk>  reentry<unk>  tachycardia usually occurs either in patients with structural heart disease or in patients with conduction disturbances with a structurally normal heart.<unk><unk>  reentry is a macro-reentrant tachycardia that incorporates the His-Purkinje system, the<unk><unk> es, and transseptal myocardial conduction in the circuit. Typical<unk><unk>  reentry tachycardia uses the right<unk>  as the anterograde limb and the left<unk>  as the retrograde limb. Atypical<unk><unk>  reentry uses the left<unk>  (anterior fascicle, posterior fascicle or both) as the antegrade limb and the right<unk>  as the retrograde limb. The tachycardia appears as a typical Left<unk><unk>  Block or Right<unk><unk>  Block.
