Can thyroid medicine cause ectopic (skipped) heart beats?
I started Levothyroxine .5 mg last Fall for underactive thyroid. I noticed shortly after taking it that I had heart flutters. I looked at the symptom packet just out of curiosity and it said that it could be a side effect.
Well, fast forward 9 months, I've still been having them but sometimes it's more of a skipped beat. I have a rush of dizziness with them and sometimes some pain.
In the last 6 months I've had 5 EKGs (including one today). An echocardiogram and wore a 24 hour holter monitor that all came out normal.
Today I had a brief moment of numbness in left arm and dizziness so I went to urgent care where they did the EKG. Doc said it was prob a skipped heart beat.
Does anyone else have this or what's going on? Do you think if I took the brand name Synthroid or whatever it's called that these may stop?
Any help would be appreciated. Thank you.
