If the retrograde limb of the circuit is the fast pathway, it is deemed typical; if it is slow, it is atypical. Typical AVNRT is much more common (90%) and involves a slowly conducting antegrade limb with a rapidly conducting retrograde limb ( slow-fast variant).

WebbEsistono alcuni tipi di AVNRT. La "forma comune", detta anche slow-fast, utilizza la via nodale lenta come braccio che conduce gli impulsi al nodo atrio-ventricolare e quindi ai ventricoli (braccio anterogrado) e la via nodale rapida come braccio retrogrado che veicola gli impulsi agli atri. how to run sims 4 cc through hard driveWebbSlow-Fast AVNRT (Common AVNRT) This form of AVNRT accounts for 80% to 90% of cases of AVNRT.
