Can you explain how the cardiologist diagnoses a patient with wpw?

Yes, I can. Wpw is diagnosed mostly on the ekg. The major portion of the ventricular activation, the qrs, has a delta wave associated with it. Also the delay between atrial and ventricular activation is abbreviated so the time between atrial acitvation (p wave) and ventricular activation is reduced. At times in the er patients come in with tachycaria which leads to the diagnosis.
Yes. I agree with the answer previously given, but there are also people with WPW who do not always conduct the electrical impulses from their atrium to their ventricle through the accessory pathway (the abnormality in WPW is the presence of this accessory pathway) and in these patients sometimes when the suspicion is high an ep study is needed for the diagnosis.

Is a Junction rhythm ok in a six year old patient? She has short p-wave intervals. Cardiologist says not WPWS or Longe Guion. Says nothing to worry about

Specialist. A pediatric cardiologist with expertise in cardiac rhythm would be best qualified to answer your question, but I believe that the junctional rhythm in this child falls into the category of a normal variant with little chance of causing serious cardiac dysrhythmias - tachycardia or bradycardia.
