WebWhile all cells in your heart can conduct electricity, the cells in this system conduct it at very specific speeds. This is how different parts of your heart beat at just the right time. The … WebAV accessory pathways, as well as AV nodal bypass tracts, generally exhibit “all or none” conduction behavior during electrophysiological evaluation. Rapid nondecremental conduction up to the point of refractoriness is the norm and is exhibited during antegrade and retrograde conduction, especially when competing AV nodal conduction is absent.
