Today I went to my dr. for the results to my thyroid test. I have been diagnosed with Hypothyroid for almost 10 years now and put on and off medication for years. During this visit, I explained to him this chest sensation I have been getting off and on for a few months now. It feels as if theres a bubble stuck in between my breastbone. Almost like I have to burp, but not able to. He set me up for an EKG. The results came back abnormal and he said that by looking at the results, he thinks I may have a slightly enlarged heart. I am shocked by this. My last EKG in Dec of 2010 came out completely normal. Is it possible that these results may be false?

I am only 28 years old. I dont smoke, never drank in my life, never took any drugs, and my blood pressure was normal today (128/79). The only thing I have against me is my weight. I am quite overweight, about 100lbs. I'll admit prior to this, I did not take care of myself at all for about the last 2 years. I would not monitor what I ate, go to bed at 5am, and lived a completly sedentary life sitting in front of a computer screen for 8+ hrs a day. I finally got sick of it and started an exercise routine 5 times a week about 3 weeks ago and have lost 12lbs since then so I am working on bettering my health.

My questions are: Is it possible that I was givin a false postive? If I do in fact have an enlarged heart, should I worry? Is it reversable? Can I die suddenly from this (watched too much Dr. G, =\ )?

Thank you
