  • *ventricular pre-excitation considered at low-risk if ≥1 criteria satisfied: 1) sudden disappearance of pre-excitation during exercise; 2) at electrophysiology study refractory period of the accessory pathway >240 ms at baseline and >200 ms during isoproterenol infusion.

  • †in the absence of an underlying heart disease.
