My 15 otherwise healthy daughter began having very rapid very hard heart beat episodes about 6 months ago. It frequently happens when she is just getting out of the shower, though this is not consistent. She saw a heart specialist who put her on an event monitor but concluded the episodes were not that abnormal and some people are just more aware of their heart beat . I (and my daughter) was shocked and scared by his diagnosis (or lack of). When I told him I had felt one of her episodes and it was definitely abnormal! I told him she was not exercising when it happened and it was pounding hard at, at least 200 beats per minute. He only suggested we repeat the monitor. I asked if there were tests we could do and he said No, not really . My daughter is scared and I am terrified! What can this be??? She is a very level headed child and not at all prone to dramatics or anxiety . She does have IBS and is allergic to nickel. The only other medical history she has had is Amblyopia . Her family doctor initially did an EKG ( stress test) in office, though it was done with her resting heart rate and it was normal.
