I suffer from CFS/Fibro/Dysautonomia/SVT's or MVPS. The DR's are not really sure which one came first, CFS or Dysautonomia. I believe it's Dysautonomia because I was born with Mitral Valve Prolaspe and rapid heart rate (so my cardiologist believes). It was picked up after the birth of my daughter, 2nd child. Many years I went through this fight or flight thing, caused by the SVT's that probably damaged my immune system which caused the CFS. So the theory is, let's fix the SVT's (hopefully), through an ablation which may improve the CFS but not cure it. My body has suffered some damage of living like this for years, since childhood. When someone suffers from SVT's the first thing DR's try and tell us is: It's panic attacks and we need to go see a therapist. I don't need to tell anyone here the long list of DR's I have been to through out my years. You all know the pain because you too if you are reading this have been there or are probably there now. I'd like us all to know and believe there is HOPE. It's been proven that I suffer from SVT's because of the event monitor I have had to wear on more than one occasion. My Cardiologist told me that for years many DR's ignored the racing heart and went right after the label "panic attacks" etc. Therefore, the problem was never fixed and hundreds of thousands of people come down with CFS/Fibro/Dysautonomia and the alike health problems. If our body is always going in and out of the "fight or flight stage" due to SVT's, physiological not psychological, you can imagine, what this can do to us over a period of time. It throws our system off balance which can cause many other symptoms. I share this with you because anyone who does have this symptom often should have this really checked by a good Cardiologist. I'm not suggesting that this is what it is, I am informing you of my years of experience of what I have had to live with. If I can help just one person, then that person will touch someone else and so on.
