My son is 5 years old. When I was pregnant with him, the first 3 ultrasounds, starting at 6 wks showed what they called "heart defects." I was having major problems...bleeding and pain. They told my husband and I that I was having a miscarriage. I ignored them and stayed off my feet,at about 12wks, my cervix closed and everything disappered. I had a new doc and everything was ok. Over the past year, I have noticed strange symptoms in him. The first time...he came to me and said he was having a heartattack. I listened to his chest and it was rapidly beating, it sounded like it skipped a few beats. It occurred again and each time he has to go rest. Last night, he was squatting down to draw a picture, no physical activity...he jumped straight up screaming and crying that his heart was hurting, he said a "lobster was pinching it." I listened to it, it was rapidly beating and it skipped a few beats, he rested and it went away. Should I be concerned about this, He's had 2 pediatricians and they said his heart sounded fine. We have moved to a new state and haven't found a doc yet. I don't want to seem paranoid, but, I'll always think about what those first ultrasounds showed.
