Im 38 years old and have had this problem with my heart doing weird things for nearly 2 years now.It gets faster and then irregulates with heart palpitations that are so strong that its really scarey.Ive had the heart holter on and they didnt detect anything too abnormal.Its alot worse when i try to sleep or lay down.I find that i dont sleep at all nowadays because of this problem.Please help if you know anything.
