Webb13 sep. 2024 · EAMs were analyzed for slow pathway (SPW) and fast pathway (FPW) activation. A pivot point (PP) was defined where FPW and SPW collided and pivoted back to the AV node (AVN). Conduction was assessed with programmed extrastimulus (PES) in 9 patients until FPW refractory period (ERP). Webb15 maj 1995 · Participation of the slow or fast AV node pathway as the antegrade limb of AV reentrant tachycardia was determined by comparison of the AH interval during tachycardia with that observed during slow AV node pathway conduction with atrial extrastimuli, incremental pacing, or AV node reentry. Webb27 aug. 2024 · A fast path is a path that's fast (i.e. does less work), and a slow path is a path that's slow (i.e. does more work).

Webb3 apr. 2024 · Slow pathway (SP) ablation is a well-accepted procedure for treatment of atrioventricular nodal re-entry tachycardia (AVNRT) and non-reentrant AV nodal tachycardia in adult and paediatric populations. Webb1 feb. 2015 · Slow Pathway Tachycardia With Retrograde Block. Tachycardia may arise from the slow pathway input to the AV node but exhibit retrograde block such that atrial activation occurs only via compact AV nodal activation and then retrograde activation via the fast pathway thus mimicking the pattern of AVNRT.
