In brief: Pre excitation

Preexcitation syndrome is due to the presence of abnormal accessary conduction pathway between atrium and ventricle.
It could lead to uncontrolled cardiac arrthmia with rapid heart beat. Premature beats from atrium are more benign and not dangerous like preexcitation. The drugs that we use for symptomatic premature beats are contraindicated for preexcitation.
