I had palpitations the last 3 years, increasing in frequency (first every 13th beat, than every 10th beat skipped, down to every 3rd beat or so)... They did full checks (3 sets of drs, two countries, including an angio) and while they acknowledged their existence, they said "your heart is fine; these ectopics happens"... But in the meantime, I was assigned 3 rounds of completely different medicines, some quite strong (rytmonorm) and affecting me (feeling of constant pressure on my chest), and finally very mild (darob= stalol hcl), which I liked.
After about 1 year on Darob, I got somewhat relaxed thinking that I got it checked and they found no problem, so let me ignore it. Then, 2 weeks ago I had a very long bout of flu where I coughed a lot and deep, and when I went to the doctor, I reminded him about arrythmia and my medication, and when he said let me hear them, they were almost gone (one every 30-40 beats). Now I do feel the flutters from time to time, but almost no palpitations or ectopics that I can detect from hertbeat.
Hope this helps someone as a positive example, even though I have not written in good detail...
