My 4 year old Daughter has random rapid heart beat. It will occur even at times when she is not active, even upon waking. This occured this morning. I had her evaluated at the doctor, they hooked her up to a monitor and said she is fine. However, this does not seem normal. It scares her and me. When I feel her chest it feels as though it is pounding at a rate that is abnormally high. Kindly advise? Should I seek out advice from other than her Pediatrician at Kaiser? Her doctor seems very thorough.
