Thanks for the great replies! I hope your daughter is OK. My son has focal in the parietal lobe on EEG. What is ablation therapy and PSVT? Does it have anything to do with a long PR interval? I am grateful for the info about possible misdiagnosis. The epilepsy meds might be helping my son because he hasn't had a spell in a while but they come in waves. We recently went to a cardiac electrician who now thinks it may be a vagus nerve problem related to the epilepsy not WPW. Of course they want to do another monitor thing for a month and then a slew of other tests before proceeding to the one that absolutely rules out WPW. My son is turning 18 and has lost his health coverage so we are self-pay and wants to skip ahead to the cath-type thing which is the absolute decider (I think they fix it then too if he has it) and I can't blame him. I'm worried about the vagus nerve thing, because I read a little about the implants... I don't know if that is what they are thinking he might need if not WPW...wrong to be scared about that?
