                        I also have a rapid heart beat.  I have had to live with it for many years now.  I also get flutters with it. I have found that if I don't drink cafine,get plenty of rest and control my nerves, then it doesn't seem to bother me.  My mother also had the same thing.  It seems to run in families.  I notice it more when I lay down also.  I sure hope this will help you.
