Hi mikey
Welcome. I hope you can find some support and reassurance and help here.
Well, it does sound exactly what a lot of us suffer from - it sounds like you are having ectopics (extra beats which = palpitations). They may feel like you are missing a beat but in reality your heart has not missed a beat it has thrown in an extra one or two in between your normal sinus rhythm. sometimes you may not feel these so you might feel as if you have skipped a beat, othertimes you might feel them as flutters, other times you might feel it as a harder beat. All of these are the same thing really.
Just make sure you are checked out properly by your GP.
Yes, the ECG thing... unless you are having ectopic beats every few beats then they probably won't be picked up on an ecg (mine are so frequent they are often picked up in a 15 second ecg.) But apparently GPs are not really interested because if the ecg shows as otherwise normal, they are not a big deal to the doctor. They might be for you - but that is another story... and why this forum exists
Many of us here have weird things that happen to our hearts every day - mine has been going on for about a year and a half now. I get thousands of ectopics per day and other weird happenings. Drives me mad, but the doctors say it is not dangerous so there is nothing they can / will do.
Just stay as healthy as you can and try to be relaxed about them - easier said than done.
I wish I could tell you how to get rid of them - I have tried all sorts - yoga, relaxation, antidepressants, no caffeine or alcohol, beta blockers, CBT. All of these things - nothing has worked. I am now getting fit and on a gym program (3 months so far) - purely for heart and lung fitness as I have no weight to lose, so it's ongoing and may show some benefit at some point in the future.
