For the past two, years there have been five, maybe six times, where this has happened. It's completely random, it seems (as it just woke me from my sleep) and absolutely terrifying.
My heart will start beating extremely irregularly, like instead of it's normal tha-thump tha-thump, it just beats in random, fast-paced bursts. (thump th-th-thump th-thump thump) This has lasted anywhere from 5 minutes, up to around 30 (today), is very painful in the chest area, and causes me to become short of breath and lethargic almost to the point of not being able to move.
I went to the doctor about it last year. He referred me to a specialist who then put me on a heart monitor for a couple weeks. Unfortunately, an episode didn't occur while I was hooked up to the thing, and they told me I was fine, much to my dismay.
It scares the hell out of me. Should I see another doctor? What the heck is going on?
