The fluttering in my heart, presumably caused by my MVP, is constant lately. It is causing me to feel mildly lightheaded and is giving me a minor headache. I ve had MVP since I was about 10 years old, I am now 22 and I have never experienced this constant of a flare up in the fluttering. It s happening more often than not and I become flushed for a brief moment after each episode. Any idea why this is happening? Should I be worried? Thanks!, Julie
