Webb14 nov. 2024 · Slow pathway modification using an anatomically guided approach is now established as an effective method of treating atrioventricular node re-entry tachycardia. 1-4 Previously, fast pathway ablation has been described but slow pathway modification is now the preferred approach because of the lower incidence of AV block. 1 3 5 10 11 … 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.
