In brief: Pre-excitation

Wpw syndrome is commonly diagnosed on the basis of the surface ECG in an asymptomatic individual.
In this case it is manifested as a delta wave, which is a slurred upstroke in the qrs complex that is associated with a short pr interval. The short pr interval and slurring of the qrs complex is actually the impulse making it through to the ventricles prematurely (across the accessory pathway) withou.

In brief: Pathway

The impulse is conducted through the accessory pathway which conducts fast er than he normal av node.
