Hello, this may seem like an odd question, but please allow me to explain. For a couple of years now, since my hashimoto's (thyroid disease) diagnosis, I have been complaining of feeling palpitations or missed beats, skipped beats etc. I have had numerous ecg's and been in the ER on a couple of occasions because the 'episodes' can really be intense some times but medics never seemed concerned, despite them causing me great disruption to my life and obviously causing distress.
One time, the weird floaty feeling and 'skipping' was so awful that I ended up having a panic attack out of worry and had to go to the ER because after querying what was going on with me, they wanted to check me out just to be safe. Again, they did tests, bloods and ecg and said all was fine.
I recently found myself up at the walk in centre again, due to many disturbed nights with this feeling of fluttering and skipping in my chest and this is the ecg that they ran. Please see pic. I was having the sensations the whole time I was on the monitor.
They diagnosed sinus arrhythmia and tachycardia. I was glad that my heart continued to 'perform' its tom foolery whilst strapped up to the ecg as at least they got to see what was going on. But my issue is that I read that people don't know they have sinus arrhythmia so how come I can literally feel every miss timed beat!
I have periods where the arrhythmia doesn't seem to be present and it is bliss but the off putting beats are a part of every day none the less. Sometimes it is gentle enough for me to dismiss and get on with my life, but at other times, it seems to come on full force and it feels like ectopic beats, about 6 or so a minute. My heart is beating normally it seems, then there is a longer than normal pause and then a floaty, sickly feeling followed by what feels to me like a stronger, more powerful beat. I always thought I was getting typical ectopic beats but they are showing on the ecg as just normal beats that are out of their normal rhythm. If sinus arrhythmia is just the speeding up or slowing down of heartrate due to respiration then why does the heart seem to stall and skip as it changes pace?
What triggers the episodes is tiredness, eating, (it can sometimes stop me from eating my food as it is not pleasant while you try to eat and often subsides about half an hour after food.)Not eating, stress and generally moving about also trigger it. If I sit still, I can have a good period of quiet but once I get up and start moving around, they start again and I can feel the fluttering going on. Exercise is uneventful and life is normal on the bike which is curious.
They said that this is nothing to worry about and I have read that it is related to breathing cycle and I can certainly relate to that as when I take deep breaths, it also seems to trigger a 'skip' and if I hold my breath when I am getting runs of them, they happen less.
What I didn't realise though is that there are two kinds of sinus arrhythmia and that one can be a sign of heart damage but they never said which type I had and they wrote simply sinus arrhythmia on the ecg print out and not Respiratory Sinus Arrhythmia. I am also 44 so why have I developed this now if it is mostly a young person thing?
I just wondered if anyone else has this and can you feel it too? They put me on propranolol, just a low dose (10mg) and the beats are softer and more fluttery and without the big thuds that were keeping me up at night, but it still makes me feel woozy and sickly as this feels like I am constantly going up and over a rollercoaster.
Also, any ideas why this has got worse in the last few years and is it possibly to do with my thyroid as obviously there is a connection to thyroid and heart regulation. I used to get the odd skipping feeling several times a day a few years ago, but now I get so many it can stop me from getting to sleep which often makes it worse the next day. I eat well and exercise and wish I could just understand why my heart does all this crazy activity because the ecg just doesn't do justice to how much this has impacted my life. I have removed as many triggers as possible, no caffeine, no alcohol, reduced stress and try to sleep when it lets me but I have lost weight from sometimes not being able to put food in my mouth without it signalling to my heart to go crazy! It doesn't seem to be any particular food either, just more about the amount or the calorific value.
Thank you and sorry for the rambling on. I don't seem to know how to make a long story short!
