Wow, I'm surprised how many replied and have similar experiences. There are a few things I'd like to add, because I did learn some things in the last 7 years since it started. - Cognitive-behavioral therapy did not work for me. The thing is, as soon as your heart wants your attention, you're submissive. I talked a lot with psychologists, but it didn't get better. - Running to the ER and being dismissed with good blood samples helps. But only for a limited time. - Stress is very bad. Not long ago I had a very arduous business call with a former co-worker and I felt one extrasystole after another. As if my heart would want me to calm down ;) - SSRI (e.g. Escitaloprame) are really powerful. They did not cure my extrasystoles, but they prevented things like panic attacks. Side effects are note worthy though, you pretty much lose a lot of your sexual energy. - and if you're into medicine, SSRI may also produce new cardiac problems, such as QT-interval prolongation. It's a vicious circle. In the end, I think, the heart is much, much more than a muscle. I always hope that someday I'll find a doctor who gives me the answer I'm searching for so long, what exactly is causing all this.
