Wolff Parkinson White Syndrome...

My name is Brooke and I am 22 years old. I was diagnosed with Wolff parkinson white syndrome after my second pregnancy. I was experiencing dizziness feeling a fluttering in my chest and nausea and almost passed out at work so I went to the ER and then was referred to a cardiologist. I had an echocardiogram and did a 48 hour holter monitor which confirmed WPW. My doctor then referred me to a larger hospital so I could have a Catheter ablation. I had the ablation done 6 months ago and post operation EKGs showed that it was successful. I went about my life as a normal 21 year old and up until 3 months ago I felt fine. Here is where I get confused and in all honesty a little concerned.. it started like I said about 3 months ago, I was working a fulltime factory job and I noticed I was getting sick a lot.. nausea mostly but sometimes actual vomiting. I blew it off as a virus like a stomach flu type thing.. then new symptoms kept adding to the nausea every few weeks. Dizziness, lightheaded, just a general sick feeling. I still thought it was some kind of bug. I lost my apetite, lost about 20 pounds and Now about 3 weeks ago I started feeling really weak. I would be folding laundry and my arms would just give up. They were sore like I just did a bunch of push ups or something. My legs are so weak I can barely go up the stairs without needing to sit down, I am out of breath after doing hardly anything. My heart feels like its pounding so hard I am going to have a heart attack and whenever I do anything physical my chest hurts like a dull ache feeling. I went back to my doctor and he ordered another echocardiogram and another 48 hours wearing the holter monitor I haven't gotten those results back yet. All my blood tests came back normal. Not pregnant. Normal thyroid levels. Has anyone with WPW Syndrome felt this and even after a supposed successful ablation? Please share your experiences. Could there be something else wrong with me?
