Hello RLR,
I have printed out your wonderful explanations about palpitations.  
As of this last April, I just have not felt well at all.  In the month of May, I had a two week fever (which was going around our area).  Then, after power mowing our teeny back yard, and I mean a small back yard, I got huge and on going palpitations (about 10-15 mins).  I went into a panic attack and now, no matter what I do, if its strenuous, I get palpitations.  My doctor had me wear a Holter Monitor and said there were only two odd beats that were seen in that 24 hour period.  Now, when I walk hurridly or do much of anything,I get the palpitations.  Can this be anxiety related or wasn't something more omnious caught on the Holter and I should get it checked out further.  I am 64.  Thank you for answering me.....I have also had panic attacks for the last 40 years and am on no medications for it.  I am also taking Tenormin but just 12.5 mgs to help with the thyroid issues, (Hashimotos) and just recently was told to increase my synthroid meds for that.
Again, I just need a kind voice in the mud of my life!

Thank you for your time, LR3216

Hi Saab,

Years ago I did have ekg's and even the stress tredmill test and all was fine but that was probably 10 years ago.  This is just different in that I can't even help husband dry off the car, without going
into palp mode.  I see other 64 year olds and they are golfing, major yard work...etc....and i just
cannot do that anymore.  I have never been one for exercise (ask my husband) but have loved yard work., etc.  

Yes, all of the Claire Weekes books are my bibles and they are sooooo dogeared its unbelievable.....but as I said, this is seems like its beyond the norm of panic attack.  Last night we walked up a hill after a concert and it just did flutter type palps which was also not the normal kind that I have been feeling.

I do hope RLR will give me some advice.  Here I sit, feeling sorry for myself and wondering what this is really all about.

Thank you again for your advice about the book.

Hi angiebaby!
Wow, 37 and you are just in the same mudbath as most of us are!  All these palpitations just play havoc with our minds so much and the moment we mention the word "anxiety" we are tossed into the "ignore" box!  When this is real and it affects your life and all your thought processes.....I just want to toss it over to them and say, here now you try this and see how it feels!

Sending you a feel good hug today and thanks for your reply!  Maybe some magic will happen and a special pill will be formulated to take care of these dreaded palps!

Hello and welcome to the forum.

The onset of a panic attack subsequent to the experience of palpitations is quite common, particularly if the person directly equates the event with heart disease. You mentioned that you have had panic disorder for about 40 years but did not mention whether you've ever experienced palpitations as well.

At this point, my response would somewhat depend upon more clarification. If your synthroid has been increased prior to the palpitation events, then together with the Tenormin, it would serve to explain why the occurances are taking place in the presence of strenuous activity. One of the classic side effects of synthoid is the presence of palpitations, particularly when either establishing a therapeutic dose or increasing it. Remember that the thyroid acts upon metabolism and can effect the heart rate. Tenormin, a beta blocker, even in mild doses can act to create a threshold of the sinus rhythm of the heart. In other words, without the medication, the demands placed on the heart are responded to with a corresponding increase in both heart rate and cardiac force to whatever extent is necessary to compensate. While taking beta blocker drugs, there is an effect upon this upper threshold. It does not mean that your heart will fail, but rather that it will only compensate to a certain exent, the consequences of which result in oxygen debt and quicker fatigue.

My guess here is that the recent increase in synthroid is mainly responsible in your case. I wouldn't give this any concern where heart disease is concerned. I do advocate, however, that you limit outside strenuous activity that is particularly associated with exposure to heat. Synthroid can cause heat intolerance that rather sneaks up on some folks. Stay well hydrated and limit exertion under such conditions. Also, achieving maximum therapeutic benefit from synthroid is sometimes a trial and error process, very dependent upon symptomatic response of the patient. If the palpitations become more frequent or cause you to limit your activities, then discuss this with your primary care physician. A determination can be made whether up or down-regulation may be warranted, but the side-effect may be temporary and subside with continued use at the present dose.

I would give a little more time and ease into your regularly attended activities to determine whether the symptom dissipates over time. As I've discussed monitoring results before on the forum, we can see many things on the test strip that would indicate the presence of heart disease and it's not necessary for us to actually see the palpitation events to know whether they represent something "ominous."

If the palpitations continue, then your doctor may consider either a physical or chemical treadmill test to help determine whether sufficiency is being challenged, but at this point I'm still leaning more toward the recent change to your medication regimen.

You'll be just fine.

Best regards and Good Health

Well, you shouldn't feel scared or more concerned. I see nothing among your description that would cause me to consider the prospect of heart disease. In light of the presence of both panic disorder and Hashimoto's disease, there are perfectly rationale circumstances for the presence of palpitations.

The clarification regarding your dosing for Synthroid does not suggest another more sinister cause for your palpitations. The holter monitor and other diagnostic tools are very capable of detecting the presence of heart disease that would initiate the onset of arrthymias.

Again, I just don't see anything here that warrants fear of heart disease. Enjoy your birthday celebration and plan on many more. You're going to be fine.

Best regards and Good Health
