Hi everyone , I am a 19 year old female that has been having a problem with a fast heart rate for about 2 years now! I've had a echo & holter monitor . Only thing they saw is that I have sinus tachycardia (No clue why ). Was put on atenonal 25mg , Stopped due to weakness & fatigue . I had test done in the er lastnight . came back with low potassium 3.0 & Magnesium 1.7 . Also they checked my TSH which was elevated at 5.03. Still no diagnosis & unable to see my doctor until the 8th . idk what else to do I feel absolutely horrible ! Could this be something postpartum , I just had a baby 4 months ago? I need help . PLEASE !

Hi Cuppie, Welcome to the forum.  Sinus tachycardia can be hard to pin down but is generally caused by something outside the heart.  Electrolyte imbalances, especially potassium and magnesium can have an affect on the heart so maybe consider taking some supplements until you get them back up.  Eat more bananas.  Generally hyperthyroidism is sometimes a cause of an elevated heart rate but it is usually from low TSH levels as opposed to high which is more indicative of hypothyroidism though further tests may need to be done to dig deeper into your thyroid issues.  It is possible they are only off due to the baby.  It takes quite a while for the hormones to regulate themselves and maybe longer after having a baby.  I am not sure but talking to your gynecologist may give you some answers.  Unfortunately you may need to wait to see your doctor to get more answers.  Until then try to drink lots of water and avoid caffeine, sugars and carbohydrates and try to not eat super huge meals and see if that helps your rate come down.  If none of that works then maybe see if you can be checked for POTS or Dysautonomia.  It's trial and error though to figure it out.  Just keep at it and you will hopefully find the cause and feel better.  Sometimes getting in more cardio alone does the trick.  Best of luck sorting it out and keep us posted on how you are doing.  Take care.

What are your numbers? I'm going through the same thing. Except I was not put on medication. I just found out about it because I had a surgery and the heart rate was never under 90. But looking at some old urgent care and er papers my hr has always been in the 90's. Which is pretty scary even though my cardiologist said anything at 100 or less is considered normal.

Pixiee27 , my hr is usually around 120 when doing normal activities . I measured at rest & its around 83. I'm starting to get worried because noone is telling me anything & I have to wait to see a doctor (I already have aniexty in general , which could also be contributing to it).

I see that you have a rate in the 80s resting.  This is pretty normal so it could just be some lifestyle issues like I mentioned before that could help you feel better.  Drink more water, avoid sugar and heavy foods and get some exercise.  Get your potassium back up and work on your stress and anxiety and you will like find your heart bothers you less.  But a rate in the 80s resting is pretty normal.  It is likely just that you are noticing it now more than you use to.  Try to not hyperfocus on it and that in and of itself may help.  Deep slow breaths.  Take care.
