Need some input

My doctors visit today may have taken me 10 steps back! I thought I was threw with the nerves....but they are in full swing now.

I went back to the EP today. She checked my recordings. It said I was in the 140's from 10am-2pm. I felt fine! I was just running around at school etc. Then at 2 I rested in my daughter. The RHR went down. Then she said it went back up to the 140's from 3-4:30. Again, I was just running around getting the house ready for a babysitter etc.

Her gut says it's my thyroid medication. But I explained to her that I have an underactive thyroid and I am still not even taking the high dose of Synthroid that they want me to. So she wants me to have a thryoid panel done ASAP.

She also prescribed me a beta blocker. 25 mg of Atenolol. At first she said it when I started to feel uncomfortable ....but I told her I didn't even notice the 140's today. So then she said take it daily for 2 weeks, get my thyroid work done and come back in 2 1/2 weeks.

She basically said my heart is working too hard to just be running around doing errands, that it's at a treadmill rate. I am thin as well...possibly too think so she was saying that my heart was working so hard I could not possibly eat enough food to gain weight at this point.

I am worried because I know a fast heart rate for an extended period of time IS NOT GOOD.

Please help

Do you know if your pacemaker's Rate Response is ON or OFF?

Sometimes that can be the culprit of making one's heart go faster as I understand it.

It's a question worth asking if you don't know if its on or off PLUS it has different ranges...low, medium, and high.

This just MIGHT be a factor in what is going on with you.

Electric Frank can explain it SO much better than I.

Good luck.

My RR response is turned off but I did come home ad research hypothyroid and taccacaria and here is what I found:

Dr. Ray Peat: In hypothyroidism, thyrotropin-release hormone (TRH) is usually increased, increasing release of TSH. TRH itself can cause tachycardia, "palpitations," high blood pressure, stasis of the intestine, increase of pressure in the eye, and hyperventilation with alkalosis. It can increase the release of norepinephrine, but in itself it acts very much like adrenalin. TRH stimulates prolactin release, and this can interfere with progesterone synthesis, which in itself affects heart function.

I consider even the lowest TSH within the "normal range" to be consistent with hypothyroidism; in good health, very little TSH is needed. When the thyroid function is low, the body often compensates by over-producing adrenalin. The daily production of adrenalin is sometimes 30 or 40 times higher than normal in hypothyroidism. The adrenalin tends to sustain blood sugar in spite of the metabolic inefficiency of hypothyroidism, and it can help to maintain core body temperature by causing vasoconstriction in the skin, but it also disturbs the sleep and accelerates the heart. During the night, cycles of rising adrenalin can cause nightmares, wakefulness, worry, and a pounding heart. Occasionally, a person who has chronically had a heart rate of 150 beats per minute or higher, will have a much lower heart rate after using a thyroid supplement for a few days. If your temperature or heart rate is lower after breakfast than before, it's likely that they were raised as a result of the nocturnal increase of adrenalin and cortisol caused by hypothyroidism.

HR

Wendy,

I can't help you with why your HR is going fast sometimes but I have been on Atenolol for many years (except for the one year they took me off because of my HR bradying down et pausing) but am back on it again and it from what I have heard and been told by my Dr.'s that it really is a pretty good drug to take if you have to. It slows down the heart so it beats more efficiently. I have never had any problems the years I have taken it and they do give it at my hospital if they think someone is having a heart attack. So just think will be a step ahead if we have one! (At least that's what I tell myself :-) I also exercise which supposedly brings your HR down too, Hope things get figured out. Carol
