I had bad palpitations on levothyroxine and the Cardiologist was puzzled about the cause and was going to put something in heart to record what was going on, mostly it happened during the night. I had a number of 'monitors' and had to take betablockers but I didn't need this op and neither did I have to have another appointment with him as it all resolved when T3 was added to T4 and then eventually took T3 alone.

I believe T4 can cause tachycardia and I think heart symptoms is also a clinical symptoms of those undiagnosed, as T3 is required by heart and brain. T4 is an inactive hormone and it has to convert to the Active thyroid hormone, i.e. T3. Neither do they test the FT4 and FT3. I am not medically qualified and only go by my own experiences.

The medical profession seem to believe that only hypERthyroidism causes tachycardia and hypOthyroid bradycardia but I think levothyroxine can also cause tachycardia. I am not medically qualified but only going by my own experience.

It depends what type of tachy it is.A.F is one sort.I have supraventricular tachy which they call non-idiopathic ie non-life threatenening!

About 3 years ago I had a very prolonged bout after adding tiny amounts of T3 after 16 years on thyroxine-only.After 5 hours GP told husband to get me to A&E.They kept me in overnight & it stopped without intervention after 9 hours.Doctors told me not to use beta blockers & not to come back to A&E if it happened again(Lovely male nurse told me to come back if I was worried)All the tests at outpatients heart clinic ater confirmed a previous diagnosis of ST.Offered me an ablation op,but after reading outcomes,decided a poor bet.

Now on NDT after 2 good years on T3-only.

Just had a record tachy episode!12 hours!Had to stay lying flat the whole time.Got up to go to A&E & it stopped.

Make of this what you will,but I get regular frequent episodes on thyroxine & also,constant ectopics.

I am convinced my tachy happens when my diagphragm goes into spasm & pushes up against my heart,triggering non-sinus rhythm.I took activated charcoal capsules with plent of water & I am sure that helped.I believe I was bloated due to a gut infection.

Will see how it goes & may need to add a tiny bit of T3 or a bit more NDT,having reduced my NDT from 2.5 grains down to 2 grains a few weeks ago,as it was over-range.

Hope this doesn't sound improbable,but I've lived with this for years & would only use thyroxine again if I had no option.

Hi Naomi8, I've had super ventricular tachycardia since my teens but now at age 55 it's become a daily occurrance. Just had an ablation but it hasn't changed anything. I manage to stop my tachy by doing what's called a vagal maneuver (usually involves crouching down and hold my breath). Have you tried that? It always works for me but can be embarrassing in crowded places!

Sorry to hear ablation didn't fix it.I decided against it when I read the reviews.Another member on here was luckier than you,though.I have been watching Youtube videos of vagal nerve stuff eg "York Cardiology"cery interesting.

I can sometimes fix it by bending over,but lying flat with no pillow works every time,usually after a few minutes.

My best fix is avoiding thyroxine,however.

I am concerned to read of thyroxine being added to NDT to get the proportions right.Am also concerned about the ever growing popularity of NDT possibly leading to companies doing this without declaring it,due to shortage of pig hearts.I believe the reports of poor response to "reformulations"of NDT may be due to these issues.

I don't know where you read of T4 (thyroxine) being added to NDT. I wouldn't think of doing that. I also don't know what you mean about the "ever growing popularity of NDT " because NDT is the very original thyroid hormone replacement, first introduced in 1892 and before that we died a truly horrible death due to a myxedema coma.

From 1892 up until the 60's NDT was prescribed until it was withdrawn by the BTA et al which has made False Statements about it.

Big Pharma introduced blood tests along with the new product - T4 alone - levothyroxine which is an inactive thyroid hormone which has to convert to T3 an many of us don't convert a synthetic T4 into T3 and it has slowly overtaken NDT through monetary rewards in some countries for doctors to replace a pill that had T4, T3,T2, T1 and calcitonin and made from animals' thyroid glands' ever growing popularity of NDT.We recovered without any blood tests and doctors only considered our clinical symptoms and knew all of them.

We can live and recover with T3 but many cannot improve at all on T4.

Also thousands of people recover with NDT especially if T4 doesn't agree with them.

Patients in the UK used to get NDT prescribed by their doctors - as they did T3 - but both have been withdrawn - the NDT through False Statements made about it by the Associations. They never did respond to the Scientist/Researcher who sent them the following before his untimely death.

I wish I could remember where I read that some manufacturers of NDT may be adding thyroxine to their NDT to adjust the proportions.

The ever growing popularity of NDT I am referring to is the growing numbers of us in the self-help communities like this one,who are returning to NDT,after being failed by T4 monotherapy.

Hopefully,the population of pork eaters will always ensure enough pig thyroid to go round.I hope the manufacturers will be able to keep up with the growing demand.

This planet's population is a lot bigger than it was in the 60s & hypothyroidism is on the increase.Not to mention people are living longer...

There is an NDT that is made from grass fed New Zealand cows.

I think you might find it was diogenes who posted about that right here on this forum.

Low T3 and low iron and/or ferritin may cause tachycardia.

I had tachycardia after my TT . I was dosed with high T4 (Levo) for suppression purposes .I concur with the above members great suggestions . Lowering my T4 and adding a small dose NDT for my T3 mix and raising my Iron levels helped with my tachycardia . The heart has T3 receptor sights as does the brain and muscles etc .

In addition avoiding stimulants like coffee chocolate anything caffeinated was very helpful for me .

I would suggest having your Adrenal/Cortisol/ via 24 hour saliva testing . DHEA-S via BW .
