What Causes Heart Palpitations While Having Low TSH Levels?
Question: Hi,
I'm a 35 year old male, with palpitations. I've had them for as long as I can remember, but became more noticeable as I got older and realized what they actually were. I've been to a cardiologist and numerous ER visits. EKG's always come back normal. My Echo came back normal and the 24hour Holter didn't show anything at all. My resting pulse when waking is usually between 65-72 and my BP is normal. I should mention that my TSH level is often low, I've taken numerous blood tests and it's usually either low or low-normal (which depends on the lab of course). My T3 and T4 are normal, so it's indicative of subclinical hyper. I do often have a slight tremor in my hands, a growing intolerance to heat and sometimes my pulse can be high at rest for no reason. My palpitations come and go, meaning that I can go days or even a week or two without feeling any and then I can go days where I have them off and on all day. They feel like skips, drops, flutters, hollow feeling. I've never had any other symptoms like fainting, chest pain, dizziness, etc while having them. I figure that my TSH level is probably to blame, but sometimes they come on and seems like they won't stop. It's just a little scary and it's frustrating that my Echo, EKG's and Holter hasn't picked them up. Any thoughts?

Brief Answer:
Nothing serious, don't worry
Detailed Answer:
Hi,
You have palpitations, but no abnormality on 24 hour Holter monitoring, no syncope along with slightly abnormal TSH levels and normal T3 and T4 levels, all this indicate, that there is nothing serious. You just need to do thyroid tests from time to time.
Of course you can discuss with your doctor to prescribe you a beta blocker, which will reveal palpitations, but my advice will be not to take anything in your age unless you're very symptomatic.
You can try to take some Mg, it also helps in case of palpitations. And if you concentrate less on your palpitations it will also help greatly.
Take care

Hi Dr. Baghdasaryan,
Thank you so much, that's very reassuring. This is what I've heard from my Cardiologist and other doctors, that it's nothing serious and just monitor my thyroid tests periodically. It's just always nice to have other opinions, so again, thank you.
