“…Antegrade pathways occur in 5–10 % of patients 1 and can be identified by the presence of delta waves indicating ventricular pre-excitation. Antegrade-conducing APs can give rise to tachy-arrhythmias by two main mechanisms: - Anti-dromic atrio-ventricular re-entry tachycardia (AVRT) with antegrade conduction through the AP and retrograde conduction through the intrinsic conduction tissue.
