Every once in a while, my heart makes a really strong and deep pump that almost makes it feel like it's dropping a few inches down my chest... But it only happens when I'm lying down, and not very often...
My father and I both have this problem. My dad has been to many doctor's about it (because he thought he was having a heart attack) and they said this is nothing to worry about. It usually happens to me when I worry about something. Then the palpitations begin.
I think one of the doctor's my dad seen said something that your heart actually gets an extra pump and then has longer to fill up before the next pump, so when it does pump again there is so much blood that it has that huge pump.
It is however linked to it
