Slow pathway ablation
Webb24 mars 2024 · Empiric ablation of the slow pathway was initially performed during sinus rhythm with a 6 mm cryocatheter (FreezorMax; Medtronic, Minneapolis, MN) targeting the region between the inferior CS lip and the tricuspid valve annulus, inferior to the ASD. Peak negative temperatures of -80°C were achieved within 20 seconds.

Webb7 apr. 2024 · To ensure safe and effective treatment, studies on local tumor ablation in bone are needed. Method Microwave ablation was performed on sheep bone, for both in- and ex-vivo settings. Both a slow-cooking MWA protocol (gradually increasing wattage in the first two minutes of ablation) and a fast-cooking protocol (no warm-up period) were … Webb22 juli 2003 · Slow pathway ablation in common AVNRT can be complicated by total AV block. When radiofrequency energy is delivered to the posterior aspect of the triangle of Koch, total AV block may be the consequence of the absence of anterograde conduction along the fast pathway or of inadvertent damage to a fast pathway abnormally located …
WebbDuring sinus rhythm, impulses travel simultaneously through both the fast and slow pathways. That which is transmitted via the fast pathway encounters the end of that of the slow, and the two are cancelled out. If the fast pathway is in its refractory period, a premature atrial contraction will only travel via the slow pathway
