Hi everyone, I'm new to this forum but stressed and trying to get some insight to determine if anyone has experienced similar symptoms. I noticed my heart rate becomes pretty high when standing three weeks ago. Went to the doctor had an EKG, 24 hour heart monitor and blood work done. Blood work determined my thyroid was HYPERactive. Heart monitor normal with highest rate at 160bpm. Doctor told me she thinks it's due to thyroid every time I stand. Last night, I stood up to walk into my house and my heart rate spiked to 189bpm. Called on call doctor (different doctor than my regular doctor) and she reviewed heart monitor again and diagnosed me with a heart arrhythmia. I'm so confused, one doctor is saying no arrhythmia and another is saying there is one? She stayed thyroid or POTs would never cause a spike to 189bpm. Is this true? What has your highest heart rates been? Is it all day long even while sitting? Mine is only while standing. Thanks!

    Hi Kelly,

    My heart rate was approximately 150 bpm when I was resting. I was given Propranolol to bring this down. You definitely need to see an endocrinologist ASAP. But please see your regular gp for the heart rate. At rest it shouldn't really be higher than about 80.

    Hi kelly92284, as mentioned by dawn31341 above, one typical symptom of hyperthyroidism is an elevated resting heart rate. On top of that, the heart might beat stronger giving the sensation of a pounding heart that does not calm down. This used to happen to me even while lying down and trying to sleep. 

    Could it be that you have a combination of POTS and hyperthyroidism? Is your resting heart rate already elevated? If that is the case then POTS could drive your heart rate up even further after standing up.  

    To get some clarity regarding your hyperthyroidism you could get a copy of your blood tests and consult an endocrinologist.

      Thanks everyone, I was wondering if I had POTs as well as Hyper because I've noticed that POTs can have a cause of Hyperthyroidism. They told me an endocrinologist isn't neccesaey needed as my levels aren't extremely high but maybe I should look into seeing one just in case.

      My resting heart rate is somewhat elevated but still normal. Before all this started it was average 60-70 bpm, now it's around 80-90 resting. However when I stand, it spikes really high....

      My Free T3 and Free T4 were not that much out of range at my diagnosis but I was sent to an Endocrinologist and she put me on Propranolol immediately even before she finished testing for hyperthyroidism.
