Teen son's heart rate

[gerrie89]

My 15 yr old son was dx as hashimoto's with secondary hypo 10/24/2006, we took him to the pcp because he was having tremors, headaches and dizzy spells. His Tsh was 10.341 so they refered him out to a endro . It took six weeks to get  his appointment with her, his TSH was then 18.50 was started on synthroid 0.1  at that visit his heart rate was then 88 BP was 138/88

Next visit 1/04/2007 his TSH was 34.3 and FT4 was .51 his heart rate was then 64 his BP was 122/78 his synthroid was upped to .137 At his 6 week blood draw she upped his dose to 0.15

Visit 3- 05/03/2007 - His TSH was  3.7 heart rate of 60 BP 122/72  synthroid was upped to 8 pills per week vs. 7

Visit 4-8/29/2007- TSH 2.4 heart rate of 52 blood presure of 116/80 upped does to .175 7.5 tablets a week

Visit 5- 10/8/2007 TSH 1.70 FT4 .67 heart rate was 47 blood pressure 124/76 still the same dose of synthroid.

My question is this, I know heart rate problems are " normal" in hypo pt's however everything I have read says that should resolve with hormone treatment and his has not. His did not start to slow down till AFTER treatment.

He has had a 48 Holter moniter test that was found to be normal except for the low heart rate which was a average of 46 bpm.

His endro is saying this is a heart problem not hypo, and his PCP is saying it is an endro problem. Should we seek the advice of a cardologist? I am real concered about this since he is still having the tremors and dizzy/and now fainting spells upon rising that he was having a year ago.

I was not trying to be " sarcastic or higher than thou mighty remarks. " as you stated I was simply pointing out that his heart rate has dropped, it has not been going up and down.
,  I think you may have missed read  my  post about his rates. The 67 you mentioned was a FT4 level " FT4 .67 heart rate was 47 "
I fully understand no one is Doc's here, and that is NOT what I wanted I was asking if anyone has had the same problem of their heart rate steadily going down and not coming back up.
Maybe I should of tried to find another forum since  I seem to have caused so much drama with a simple question. Which is not what I intended since this could be fatal for my child and I was just needing a little feed back.

my mother has posted over in the cardo forum also. and they are also thinking it is endro is why I came over here

I  stand corrected and do apologies.  Neither my spell check nor my  Webster Dictionary recognized this.  Next time  I shall be more careful and look in my Taber's Cyclopedic Medical Dictionary - oops! its not in there either.  Well I never claimed to be SMART ;)
kitcurious, thanks for the correction - Trivia.

The Holter monitor is named for it's inventor, Dr. Norman Holter.

You listyour sons HR  as 88, 64,  60,   52,   67,   46,  if that is not considered going up and down, then what is(?)  In an adult  HR can be anywhere between 50 and 100 and still be considered normal., it depends on the person. I don't know if a 15 year old would be considered adult under these HRs ranges.  As I mentioned, HR AND BP per medicals, change even throughout the day. Its when they go out of the above range either direction, is there a concern.

I stated about my HR which was post hormone treatment. That IS what you asked, was it not (?)

The listed Doctor forums was for your convince until you got into you own endo. beings we here are not doctors.

Yes, I know what a  halter monitor is! But seems you do not know how to spell it.

We are here to help, voluntarily I my add,  and don't deserve sarcastic or higher than thou mighty remarks.

He is seeing the endro, as I stated that is who I posted all the results and visits about. I posted  to see if anyone else has had the problem of heart rate dropping post hormone treatment since everything I have read said it should correct it's self with treatment. and his has dropped since treatment.

We also know that it is not a going up and down thing since he had a 48 hour holter monitor test done and his HR was constantly below 50. In case you do not know what a holter monitor test it is a 48 hour ekg.

In other words, my BP fell somewhat since starting the levothyroxine, though for me that was a good thing.

GravesLady is right, please try to post to a cardiology forum.
I was diagnosed with Hashimotos and when I started my thyroid replacement horomone my BP declined notably, but not my HR. One of the docs on the heart forum did answer my question and said that this can happen. I would post a question to a doctor on the heart forum with your specific details as even though they are along the same line they do differ  from mine as well.

Heart rate as well as BP, can change, even throughout the day they can very. My heart rate has gone from 46 to 76 various time through my 11 years, of course I'm old ;)    If you would feel better, go to an endo. One who works and treats many thyroid patients yearly.   If he suggest cardiologist, then it would be warranted to go or if your are not satisfied with the endo.
