Hello Everyone - I am a 34 year old female who was diagnosed about 8 months ago with hypothyroidism. Additional testing then diagnosed me with Hashimoto's Thyroiditis. My initial TSH level was 12.7, so I was I placed on 50 mcg of Levothyroxine. My TSH level is now 4.8.
I have had all of the normal hypothyroid symptoms - weight gain, muscle pain, tiredness, etc., but my biggest complaint (that doesn't fit symptoms of hypo) is heart palpitations. At their worst, I was having them for sometimes 5 - 6 hours a day. I did see a cardiologist, who did an EKG, echocardiogram, and also had me a wear an 24-hour heart monitor. After reviewing all of the tests, the cardiologist said that I had a perfectly healthy heart, and that the palpitations were most likely a result of hypothyroidism.
For the first few months after being on the Levothyroxine, I can honestly say that I did NOT feel any better. However, over the past 6 - 8 weeks, I have begun to feel more like my old self again. FINALLY, the palpitations started to subside - occurring for only 3 - 4 hours a day, then about 1 hour a day, then only a few flutters here and there. I was absolutely elated to have them gone!
Within the past week however, as soon as I woke up in the morning, I could tell I just didn't feel right. I've been having more palpitations again (an episode last night lasted for about 2 hours). It's only been a few days since the palpitations have returned, but I am scared to death that I am going to have to start dealing with them again. They make me feel awful!
I promised myself I was going to keep this as concise as possible, and looking at the above I appear to have failed. Has anyone else been diagnosed with Hashimoto's or hypothyroidism and suffering from long episodes of heart palpitations? Any help or advice would be greatly appreciated!
