… The concept of dual AV nodal physiology as the underlying substrate for AV nodal
reentrant tachycardia (AVNRT) is well established. The fast pathway (FP) forms the usual …

… Slow pathway ablation was attempted initially in 33 patients and in another two who …
uncommon AVNRT after successful fast pathway ablation. Of these 35 patients, 32 had no AVNRT …

… effective refractory period after successful slow pathway ablation. As differences between …
AV nodal reentrant tachycardia (AVNRT), we sought to characterize the effect of slow pathway …

… demonstrate the slow and fast pathways of the reentrant circuit and their … -fast) of AV nodal
reentrant tachycardia were mapped during surgery. In most patients, antegrade slow pathway …

… undergoing slow pathway ablation … fast pathway ablation (17 of 29 patients vs. 1 of 11
patients, respectively, p = 0.01) and did not predict recurrence of AV node reentrant tachycardia…

… in patients with AVNRT, the proportion of left-sided retrograde fast pathways might be
considerably higher than previously reported. In the atypical fast-slow form of AVNRT, earliest …

… During the common form of AV nodal reentry, a slow pathway (SP) is used in the anterograde
direction and a fast pathway (FP) is operative in the retrograde direction (slow–fast AVNRT)…

… During SVT the impulse travels antegradely down a slow AVN pathway, retrogradely up a
fast pathway. The AH interval measured as shown by dotted lines is 350 msec. During atrial …
