Lower loop reentry
WebAug 21, 2002 · In a series of 28 patients with 36 episodes of atypical right atrial flutter, Yang et al. found that 67% of 36 episodes was CTI-dependent lower loop re-entry, 22% was upper loop re-entry, and 11% was macro–re-entry around low voltage areas (scars) in the posterolateral RA. They speculated that upper loop re-entry was the converse of lower ... WebJul 1, 2024 · Reentry is the propagation of electrical activity which begins at one point and returns to its site of origin [ 3, 5 ]. Circular continuous activation through this pathway that consist of an antegrade and a retrograde limb such as in AV nodal reentry (AVNRT) or reentry utilizing a bypass tract (AVRT) results in a sustained tachycardia.
