Answer

The use of digoxin or verapamil for long-term therapy appears to be contraindicated for many patients with WPW syndrome, because these medications may enhance antegrade conduction through the AP by increasing the refractory period in the AV node. In addition, digoxin may shorten the refractory period of the AP, further enhancing its antegrade conduction.
