Webb15 dec. 2024 · It is now well established that there are two major pathways of conduction into the atrioventricular node, the so-called slow and fast pathways. 1 It is also well established that ablation of one or other of the pathways can cure atrioventricular nodal re … Webb1 feb. 2015 · The slow pathway is usually anatomically defined as the myocardium anterior toward the ventricle to the Eustachian ridge and tendon of Todaro, behind the tricuspid annulus septally, and just cranial to the coronary sinus ostium. 4 Although exceptions exist for any diagnostic maneuver in the electrophysiology laboratory, maneuvers related to …

WebbThe slower pathway recovers quicker (shorter refractory period) and can accept a new signal earlier than the pathway that conducts faster. If a premature beat occurs in the time period when the FP is not ready to receive a new signal, but the SP is, then the early signal will travel down the SP only prolonging the AH interval and PR interval.
